I am having alot of disc read errors from a 2 month old xbox, and was going to try the pot tweak but the picture in the tutorial isn't the same as mine. I have read that there are two phillips dvd drives. I have the VAD6035/21, I guess that the one in the picture is the VAD6011 older version. Is there a tutorial of the newer phillips dvd? The two pots are in different positions and I don't know for sure which one to turn.I'm not 100% sure that the dvd is the problem cause I have burned the same game using nero with same settings, same media and one will work and the other won't. I have also had games that load to the start screen then lock up and I've extracted the iso and ftp them to the hdd and the game locks up in the same place. This makes me think that it's the game that has a problem. Do some games need patches to work? I have a version 1.6 with xenium s.p. ice chip 2.01 os,evoxm8+ 16 bios,seagate 120 gb hdd locked, evox dash 3921. I know there is a newer xenium os 2.30 would that make any difference? Is there any other bios for a 1.6 xbox that would help?
