1.- Update the video drivers....
2.- check what region is the DVD (region 1 = US). You may need to specify the region for your DVD drive in the "device manager".
3.- try using antoher DVD software life DVD X Player which is region free.
[edit]
4.- I had something similar happen in the past. Chech your video drivers in device manager. I have some application install a separate video driver that caused problems. (eg
dispaly adaptors |
|--- S3 Graphics Pro savage <---- pc video card driver
|--- winvnc video hook driver <---- application video driver
5.- Also make sure on you toshiba the Bios for the TV out is set to NTSC not PAL. I thing you can check this in the control panel icon "Toshiba HW" or somethink like that with out rebooting.
6.- Update to winXP SP2 (may sure you are spyware and virus free before update). Support for WinXP SP1 end this month (Oct 31) if I recall from M$.
