I just got Sony 800UL ~ LiteOn 1693 externail. I burnt two ISOs: GTA san Andreas and MechAssault2: Lone wolf using the same program (Nero 126.96.36.199), drive and media (Sony 8x). However, the MechAssult works, while the GTA can't be recognized by xbox.
I tried using xbclone to unpack, remove any media check and repack the iso and still doesn't work.
In the past, I even use DVD+RW to succesfully burn and play any games, but it doesn't work in GTA too.
Any tips or link how to burn games into DVD+Rs?
