DVD performance software
Does anyone know of some good DVD benchmarking/tuning software under linux and windows? I want to compare performances between the two OSes since linux doesn't seem to play DVDs as smoothly as windows anymore on my system. I've tried with numerous players (ogle, xine, mplayer - self compiled). Just so everyone knows I got the best performance out of mplayer but windows is still better. I don't know what's wrong but way back when, linux used to play DVDs just fine. So basically I want to investigate the matter further. I've tried hdparm as suggested in a particular website I visited but it says that hdparm is not supported on this drive. I don't know whether that's because it's not a hard drive or because it's SCSI-emulated. Either way, it doesn't work.
One other thing I'd like to do is possibly copy the contents of a dvd to my hard drive and play it from there. If anyone knows how to make that work, I'd be interested.
Any help would be greatly appreciated.
