Ok this is what I have found when using the xbox360... in the upright position it sratches DVDs, i have the Sammy DVD player.
I have 2 DVDs I have played in the drive in the upright position:
1. Fight Night 3 - Which is now non playable, scratched to f00k.
2. Harry Potter - Now im a little ashamed to admit but having this DVD, but heck who cares.
Another thing I found when running a Movie DVD in the upright position, it would stutter, ie there would latency between loading DVD data into cache i guess. Probably due to spinning issues of the DVD.
When I play the movie with the xbox horizontal it works fine.
But that doesnt help the fight night 3 DVD which is f00ked.
M$ may you burn
Seriously though anyone else had the same issue? This, if widespread, is unacceptable, I mean feck I wanna have my lovely xbox360 vertical...
