This is the second time this has happened - she'll learn!
Originally it was running Win 7 and was able to play DVDs. However the rebuilds have had to be XP (don't ask). I've rebuilt Windows, downloaded and installed the various hardware drivers. All ok.
However I cannot get it to play DVDs. It'll play CDs but when I initially tried to play a DVD WMP said no suitable DVD decoder was installed. I installed one and - just once - a brief piece of music was played but no picture.
I've tried various DVD codecs, both free and non-free, no improvement. I've tried different media players, VLC, WinAmp, no difference. They all fail to play the DVD, just giving a blank screen.
The drive is a LITE-ON Combo SOHC-4836K.
Any thoughts on how to progress this?
An associated thought - in the BIOS the LITE-ON is shown as being on a PATA interface. If I were to replace the drive what sort of cheap and cheerful drive would be suitable?
