DVD-ROM reads CDs but not DVDs

[SmokeRingHalo]

This is an extremely old problem that I had long given up hope of finding a solution for. I simply dont watch movies on my Pc, but with more software such as GTA:San Andreas being released as DVD-ROM instead of CD-ROM the issue has come back to haunt me.

Simply put, the DVD-ROM drive wont recognize DVD media. All CD media works fine, (CD-ROM, CD-R etc.) When a DVD is inserted into the drive, the autoplay starts as the disk icon shows for about 5 seconds then stops. Trying to open the drive results in a "please insert a disk" message.

The only oddity that I have been able to find is its properties under general tab, shows its type as a CD drive. If it should be listed as DVD type then this most likely is the cause but I have no idea how to manually change its type.


My system has had many performance "tweaks" made to it such as disabling "unnecessary" services per the advice of "experts", so if reading a dvd depends on a particular service being enabled this could be it as well though ive yet to find it.
The CD and DVD drives have also been reassigned letters a few times, to the point that I forget their defaults. Currently my HD is C - floppy is A - CD is D and DVD is E. I've tryed a few combos with no success.

Any help would be appreciated in solving this 1 age old problem ive had.
If any additional info is needed for determining the cause, it can be provided.
Thanks!
