Yesterday i changed my Asus 5224A CDRW drive and my Liteon 16x DVD drive to an Asus 5232A CDRW Drive and an Asus 16x DVD Drive, the old ones went into a different computer. The new Asus CDRW drive works fine, the DVD drive does not, it's fine reading CDs, but when i try and watch dvds powerdvd stops responding or i get stuttering sound and no picture from wmp10. I've tried the drive in a different computer and it works fine. The new drive was working yesterday but is not now, i have tried every ide channel configuration, it worked when i changed both drives to the other channels, but only once, after which it went back to the way it was . I've updated it to the latest firmware version. Any suggestions, it's really beginning to annoy me. I also bought a Hitachi 7K250 (SATA) to replace my 180GXP(PATA), don't know whether that could be causing the problem or not.
