Hi, I frequent the Dux forums at http://www.duxcw.com/ and I tried my question but with no luck.
I was referred by a member there to try asking my question here.
Here's the thread at Dux in case anyone wants to read their responces and my answers to help with a possible solution:
Ok, so I'm trying to fix a freinds machine. We bought her an Artec DVD player but when we try to play any DVD in either WinDVD or PowerDVD it give us either a "No Valid Drive/Disc Found" or an "Unsupported format" error (with the newer version of WinDVD it doesn't display an error, just nothing happens when I try to play it).
The two programs weren't installed at the same time, I uninstalled PowerDVD and installed WinDVD and neither worked.
Also, when I go to "my computer" when there's no disk in the drive it reads as a "CD Drive" not a DVD drive. When I explore the drive with a DVD in it, all that it shows on it is an audio file.
I thought perhaps the drive was faulty so I removed it and installed my working DVD player that I'd been using on my system on hers and it had the exact same problems.
I also tried moving all the non-digitally signed drivers the dvd player was
using into a temp folder to see if they were causing the problem (I rebooted after the move too). Didn't work.
I tried installing and uninstalling the drives and their controllers.
I got all of the possible windows updates.
I also reloaded my ASPI file, didn't do anything.
The contoller for my DVD player is in DMA mode, I checked that.
Someone told me to just try opening the VOB file on the DVD but I can't open the vob file, if it were there then the drive would be working properly, the problem is that the DVD player is recognized as a cd player and the only file on the dvd (as recognized) is a single audio file. Here's a screen shot of what it looks like, the DVD is Amelie (I know this picture is kind of redundant since I explained it, but I like visuals): http://img35.photobucket.com/albums/v107/NeonTetra/Support/P1010001.jpg
I tried several different DVDs, that wasn't the problem and I put in a normal data disk (a game & a music cd) and they both worked just as they should.
I guess the problem is that something (the drivers, a driver conflict,
something) is causing the DVD player to be recognized as a cd device and not a dvd player.
What is involved in playing DVDs? DVD codecs, and a program, and a properly installed dvd drive? Where am I going wrong? Is there something else? I'm clueless. Does anyone know what might be wrong or what I can do to make it work?
