Utter bull-shit.
Thomson is the worst drive for compatibility some are compatible with many brands of DVD'rs others aren't (mine seems to have loaded everything I've put in it *fingers crossed*)
Samsung drives read any DVD'rs, not compatible with any CD'rs though.
Phillips is the only drive that reads CD'rs and I'm sure it's quite compatible with most DVD'rs as well.
edit: High5 @ Jack, proven Sprung wrong yet again
A friend of mine has a Philips, and it won't read anything. He has to FTP everything to his HD. It won't even read my DVD's that play fine on my Samsung.
So yeah, Philips are not reliable. I'm glad you guys have good ones though
Every Samsung I've had or come into contact with has not read CD'rs at all.
I've had bad Thomson drives that have read barely little to non of my DVD'rs but the one I have now seems to be decent.
I've never personally experienced a Phillips drive in a modded Xbox, the only time I had one the box was not modded.
Got the Xbox FTP set back up. Gonna get some skins now
