CD overburning..

Thats what they said, and Nero I know for a fact has a mode 2 setting, as well as dvd dectyptor.

Yes that is correct that you have to use mode2/XA and iso9660 & joliet for burning this iso.
But I'll repeat that again. avi's won't get any smaller than they already are on a HDD they get only bigger (only up to 1 mb) when burned onto cd.
Try to overburn with another brand cd-r. Maybe then it'll work.
Come to think of it then that's only one extra minute to overburn.

It burns mpeg or avi "movies" up to 800 mb on one cd, but its "shakey", they claim, since most readers wernt disigned to handle mode 2 cd formats.
But the Sony Playstation and PS2 consoles are designed for mode 2 cd's, ALL stopre bought, ande all but my homebrew cd's are, too. I fix them when iuse sony cd dvd generator, with citizen x's ps2imagefix, so they are right, but that makes an ISo, and I prefer those, but I'm in love with the boot image editor, and it likes bin files better (names Clay, so mine flash "ClayStation2" on bootup, it's just too classic and feeds my ego so good...) and anyway the resault is, i was doing dvxx on ps2, and I deleated a file I wanted to try again with...... and a divxx I encoded myself...and it would not copy opff the cd, not no way, "ms dos" illegal command, or some error, means the endsize file is of a greater size than windows is willing to believe in, a hippy once told me he had 10 elephants in what looked to me like a jellybean, and sure enough, 10 hand carved, super tiny elephants were in there, after all.
There are in facct almost 100mb of pure sopace on a cd-r, but the format partions and error correction allowances reserve the rest.
Playstations dont record, so they cant have errors, and follow the cd header, whatever it says the cd holds, it accepts on a disc by disc basis, that prog fromats youtr files into an image of 2058 (not positive, but 205?) bytes, and the correct mode2 file headers the ps2 is looking for first.

The ps2 should be the only reliable way to test them, actually.

Dude.. I lost you at the third line!

I have already burned over 20 divx movies the way I suggested above (2 of them on 90 minute cd-r because of their size) and they all work with no probs. except the ones with ac3 sound
max overburn with 80 min cd-rs i have ever done is somewhere 5 megs more than allowed. and it worked. but few of overburned 80 minute cd-r won´t work even when the filesize exceeded only 500kb. I think that finally one burned cd of yours should work.

once your disc is burnt then check if it works in your pc, then it should work in your ps2 also.

Okay Dex,

Just burn the Movie CD in Mode2 Format. That's also what the PS2Reality should be burned in as well.

The technical reasons are not important, but I'll try to simplify it somehow. What it all boils down to is the standard data disc selection (mode1) puts extra data inside each packet of data (sectors) on the cd to help insure that the data is transfered properly (error correction code). This is really only necessary for pure PC data because of the low tolerance a PC has for erroneous code. Any VideoCD/SuperVideoCD (VCD/SVCD) is also burned in mode2 format because that is the format a VCD/SVCD DVD Player is designed to play (plus it's in the standards) Likewise, the PS/PS2 were designed to work without the ECC placed in these headers, so you don't need it. Thus, you use mode2 format. This allows you to pack about 14% more usable data into each packet, so almost all 2KB sectors actually contain 2KB of useful data, not around 1760KB + 288 for header and ECC. (I forget the exact figures, but you get the picture). Regardless of all the technical reasons for using mode2, the only thing that matters is this: Original games are in mode2 format--anything PS/PS2 should also be in mode2 format.

i would definately not trying to overburn 713mb onto a 700mb disc. most 700mb media are able to overburn to about 715mb but its extremely risky when u are burning that high over 700mb and you could seriously ruin your cd burner. id recommend using virtual dub and taking out the credits or something burning mode2 does not apply when ur burning raw data, its not a movie cd just a straight avi file

[RAISTLIN]

GRRRRRR>>>>>>obviously some people need to do a little reading, and actually take a look at the freaking sectors of a mode 1 and a mode 2 disc. You will notice that in a mode 1 disc, nearly every header in each sector within a file will have a long section of zeros in the exact same hex location--this is the space reserved for the ECC--which is only stamped in the end sectors of each file. Burn that SAME file in mode 2, and guess what? all those little zeros get filled up with data--and you know what else? IT TAKES FEWER SECTORS FOR THE SAME SIZE FILE. Do the math here folks. Do I need to draw a diagram in your little sand box? Ok, kiddies time for class.....line up single file now...no talking!

IN MODE2 FORMAT, A 713MB AVI NEED ONLY CONSUME WHAT WOULD TYPICALLY BE ABOUT THE EQUIVALENT OF A 650MB FILE IN MODE1 FORMAT. BURN YOUR !@#$@#! DIVX IN MODE2-- NOT MODE1--YOU WILL HAVE ALL KINDS OF F*KED UP RESULTS WITH A MODE1 FILE THAT EXCEEDS 680MB ANYWAY SIMPLY BECAUSE OF THE WAY THE PS2 AND THE REALITY PLAYER WORK! DOESN'T ANYONE READ THE !@#$!@! INSTRUCTIONS ANYMORE??!!!!

Damn, that felt good to vent a bit.......

try searching google to find out if your burner supports overburning and how much can you burn with your burner.
For example LiteOn can burn up to 99 minutes (if your cd-r can take it).

OK, you guys obviously are not listening, or fail to get the point, so I guess I'll have to draw it out for you with a hard example.

I have a Video CD of SpyKids (the first one). I ran this in higher resolution and got a 826MB mpeg movie. And yes, I fit this on a standard 700MB CDR. Impossible you say? NOT! It is in Mode2, Form2. This allows for 2352 bytes per block because it removes all ECC from each block. After this "manipulation" with the CDR's file structure, it resulted in a slight overburn to roughly 720MB's. The theoretical cap on overburning a 700MB CDR is roughly 722 MB, based on the number of sectors physically available on the CDR. I was spit balling with the numbers in my earlier post and got the computations backwards, though the principle was still outlined correctly, here are the real numbers for you kiddies to look at:

A CDR is imaged based on 2352 byte blocks (Logical Block Addressing, or LBA). In typical Mode 1 format ("Data CD" selection in most burning software), each block contains an optional ECC header, followed by a portion of a file's data. This results in 2048 bytes (2KB) of a file's actual data being placed inside every 2352 byte block of data. That's a loss of 304 bytes of potentially usable data space ber block. Using a Mode 2 format (CD XA in some burning software) allows you to reclaim some of this wasted space by cramming a file's data into these slots reserved for Error Correction. This means it takes fewer blocks to hold the same amount of data on the CD. In this particular case, a Mode 1 format would require 422,944 blocks on a CD--that translates to 994,764,288 bytes at 2352 bytes/block (or 948.681 MB) on a normally addressed Mode 1 CDR! That wouldn't even quite fit reliably onto a 900MB CDR! BUT, in Mode 2 format, it can be squeezed into only 368,274 blocks at a full 2352 bytes/block to take up only 754,225,152 bytes (719.285 MB) of the normally Mode 1 addressed space on the CDR, which will fit with overburning.

By this rule, a 713 MB AVI can be burned in Mode 2 format, taking advantage of the wasted space reserved for ECC, and fit into the normally Mode 1 addressed space equivalent to just about 621MB space! That would even fit onto a standard 650MB CDR! This is how the PS2 CD's are structured--Mode2. The CD based games are actully pressed into a 650MB framework. This is why you can often have problems with anything that exceeds the 680,000,000 byte (648.5 MB) addressable Mode 1 CD space--older hardware will not recognize anything this high. Even limiting yourself to a safe barrier of 640 MB Mode 1 LBA size, you could go as high as about 735 MB in your source file when you burn it in Mode 2 format and still have compatability with the more troublesome older modchip/PS2 hardware.

So, in closing...anything to be played on the PS2 from a CD should be burned in Mode 2. Even if you are going to create DivX for playback on your PC, choose the Mode 2 format so you can get a little headroom for larger video files to increase the quality of playback.

And Raistlin's right again. I think just adding the avi to the same disc as you burn the ps2reality on, will make it fit, the ps2cdgen makes mode 2 discs no matter what, and I offered the mode 2 data cd maker for those that can't figure out the cdgen themselves, but it also offers the convenience of allowing you to leave the player files off the disc, while still using the high capacity cd feature allowed by mode 2.
THERE ARE MORE THAN 700mb ON A "700mb/80 Minute" CD-R.
That 700mb figure EXCUDES space that mode 1 cd's reserve in case of errors, so if the writer needs to, there is a little extra to account for any bytes it "scratches out" if it screws up.
Just add the movie to the player cd, it should fit.
