I'm having problems with my DVD-ROM taking an extremely long time reading a DVD when I first insert it in the drive. After I insert a DVD, the drive light goes on and the drive spins up, but it takes minutes (!) before I can start playing a DVD or before I can access data. Sometimes programs time out before they can read the disk. This is happening with commercial DVD Movies, as well as data DVDs that I've burned.
I've got a Toshiba SD-M1201 DVD-ROM (updated firmware) on an Adaptec 2940U PCI SCSI controller. The DVD-ROM drive is ID 0, terminated, parity is enabled, and it's the only device on the Bus. The SCSI controller is auto-terminated. Currently Digital CD Audio is enabled and Autoplay is disabled. Changing either of these settings has no effect.
I'm running Windows XP SP1 on a 1 GHz Intel Pentium III Processor with 1 GB of RAM. I have another DVD drive (Lite-On SOHW-812S) on my IDE interface, and I can run all of the same DVDs and data discs on that with no problem.
If someone can point me in the right direction here, I'd appreciate it.
