ESR and In The Groove –
Let me start off by saying that I am using my own original In The Groove disc.
There is a way of picking and choosing songs you want to put on this game. I'm following the instructions from this link: BoXoRRoXoRs :: Tools
Basically, it tells me to copy all the files from my original game. Then, I create a .pck file out of the songs I want to use. Add that pck file to the game files. Turn all of the files into an .iml file and then convert that to ISO. I followed every step correctly. Then, I used Memento to patch the ISO file so that ESR could run it. After using Nero to burn the ISO onto my DVD-R disc at 2x, I tested it on my PS2. Nothing happened; the disc kept spinning but the TV only showed a black screen. Next, I tried going into the ESR GUI and turned on the Disable ESR after first IOP option and it still didn't work.
Is there a compatibility issue with In The Groove? How do I fix this?
I have no clue as to whether or not that game is compatible with ESR, but I do know that several of the things you mention doing are 'iffy' to say the least.

One problem many of them have in common is that Nero makes some assumptions about normal disc formats which are not quite true about a PS2 game disc, and even less true about an ESR-patched disc. Quite likely Nero will try to 'correct' something it sees as being wrong, even though it is something required for ESR booting...
Secondly, a '2x' speed is completely unsuitable for all modern high quality disc media. It is FAR TOO SLOW.
Burning speed has a lot in common with the shutter speed of old-style photography.
Too slow shutter speed => Overexposure, leading to fuzzy and unclear photographs.
Too fast shutter speed => Underexposure, also leading to fuzzy and unclear photographs.
Only the correct speed, adapted to the film sensitivity, allowed sharp and clear photographs.
For laser burning of optical discs the case is similar, in that the burning speed needs to be adapted to the sensitivity of the disc medium.
But a big difference is that anything fuzzy or unclear will be read as digital 1 and 0 bits, and every misinterpreted bit has the potential to crash any software it is part of...
Modern high quality discs (and none other should ever be used for PS2 games) all need to be burned at an appropriate speed, which in most cases means appx half the certified top speed. So since most modern high quality DVD-R discs have a certified speed around 16x, a suitable burning speed would be 8x. But 2x is far too low for such a disc.
And if you are using the kind of disc which would need 2x for its burning, then it is sure to be of far too low quality to work for PS2 games anyway.
The PS2 lasers are quite 'picky' about the discs they work well with, and using low quality discs will not only work badly, but will also shorten the laser life span.
Some good brands are Sony, Taiyo Yuden, and my own favorites Verbatim. Nowdays I always use their "Verbatim AZO 16x DVD-R".
And I burn them using ImgBurn with a speed setting of either 8x fixed or "AWS" (== Auto Write Speed).
But that automatic setting is dependent on your burner hardware having your media type in its internal database.
So if you are not sure of that, then it is safer to use the 'half max speed' rule, to set a good burning speed.

May I also recommend trying out Open PS2 Loader with your generated ISOs? I'm one of the few remaining GH/RB PS2 hackers and it's a great way to run customized disc images (I have like 20 GH custom ISOs on my PC right now, ready to launch at an instant over the network thanks to OPL). This would also remove the need to patch the ISO after the IML2ISO process, as OPL can launch unmodified ISOs without a hitch (barring some incompatibility with specific games of course).
Not sure how it would work with ITG, but it's also worth looking into using ImgBurn to generate your ISOs. I've generated several GH custom ISOs with ImgBurn and they've all worked just fine. Kinda handy to generate and burn the ISOs with the same app. Certainly, ImgBurn is the goto app for ripping and burning PS2 ISOs in general IMO, a large number of the enthusiasts here that run Windows use it.
Ok I'm now using Verbatim DVD-R 16x and it's working perfectly! With ImgBurn at 8x, it burns the game and it runs well with the ESR Patch. ImgBurn worries me at times, though. Sometimes it tells me it can't verify the disc and other times it has no problems. Oh well. Thanks for the suggestions!
