I have a Crystall Xbox with Philips DVD drive model: VAD6035/21.
It reads quite well CD-R/RWs and DVD+/-R/RWs (Maxell, Sony, Verbatim...)
Still some discs like Packard Bell DVD-R doesn't work at all and usually DVD-R movies gets stuck!
I've tweaked the DVD drive's left pot but the improvement was only little and the drive still freezes with DVD-R movies.
Here are the drive's pot values:
Before tweaking:
Left pot: 615ohms Right pot: 481ohms
After tweaking:
Left pot: 415ohms Right pot: 481ohms
Any ideas to make the DVD drive working better?!
