PS2 has trouble playing PS1 backups

[Toccata6767]

I recently modded my ps2, i put a DMS4 S.E. Lite in it. Had a few problems at first but now it works like it is supposed to. I burned SMT:Nocturne onto a Taiyo Yuden DVD+R at 2.4x and it runs flawlessly. So then I figure I'll test ps1 backups. So I burn Lunar: SSSC at the slowest speed my burner will burn cd's(which is at 12x). I try to boot it up and it shows the ps1 logo screen a hangs, can't get past it. So then I figure I'll try a different game, I burn Grandia and it seems to work. It gets past the ps1 logo screen and shows the opening FMV, but it freezes when I try to select the load game option and in other various areas.

At this point I figure that maybe it is the media I'm using. I had been using Verbatims, which I though were good. Verbatim used to be one of the top brands, but I guess somewhere along the line they switched to CMC Magnetics for their manufacturer, which is one of the worst manufacturers, and is what I happen to have bought. So I just knew that had to be the reason my backups weren't working.

I order a stack of Taiyo Yuden CD-R's from newegg, and three days later it's here. So I go and burn Lunar, I get the exact same problem. I burn Grandia, exact same problem.

My burner is a Plextor 740A. I've got a good burner and good media. The ps2 plays ps2 originals/backups and ps1 originals absolutely perfectly with fast load times. It just has trouble playing ps1 backups, and it's not an authentication problem. The one thing I can think that it might be is that burning at 12x is too fast. I would burn at 1x if I could, but the slowest my burner will do is 12x.

Any help would be appreciated.

There is a inherrent problem with v14 consoles and dms4 lite se and the people at TeamToxic has adressed this and is planning on a fix for v14 to play ps1 games that is both pal/ntsc. I have a pal v14 and I can only play pal ps1 games and not ntsc and the same applies ntsc but in the reverse order. We'll have to wait for the next release from teamtoxic to fix this and simply update the firmware and it will probably work.

Mind you that this is a general problem on v14 with dms4 lite se, your problem could be a different one altogether.
