DVD Rom problem

I have an older Pioneer DVD-115 drive that I cannot play DVD movies on. CDs work fine, Data DVDs work fine (I can play BF2 by putting the DVD in this drive), etc.. but when I put a DVD Movie in the drive, it detects nothing.

I have a Sony DRU-720A which works perfectly fine setup in an external enclosure and USB2. I can use Windows Media Player, the ATI player from the AIW card, WinDVD, PowerDVD, etc. No problems at all. But the pioneer won't detect movie DVDs.

Any ideas on what could be causing it? I have the BIOS setup for AUTO for DMA and PIO. This drive is set as a Slave drive to my primary HD. As I have my 2nd archive drive and a CD-RW drive setup on the other IDE channel.

It'll play everything except movies? If I recall, DVD drives can be set to a DVD Region Coding. Most drives are shipped with 'all regions' activated then after X number of region changes, it locks to the last region. So if your DVD player was changed between US and Asian like 7 times, on the 8th time, Asia would be fixed and you couldn't change it.


Probably not the answer you were looking for. Perhaps you could try the same thing has Clay, complete uninstall/reinstall/upgrade of the drive?

Thanks Nuts.. Yeah, it is on Region 1, US, so that isn't the problem. I've seen alot of posts with this problem, but not solution.

It's really not a big deal. With prices of DVD players, if I 'really' need it resolved I will simply update it. For now, as long as it plays data DVD I'm OK. I really don't watch alot of DVD movies on my PC, but I was making a copy yesterday for the first time and that's how I discovered it.
