XMovie can play transport streams downloaded from the WinTV-D card and the scrawny women streams from UC Berkeley. When switching between the HDTV and the SDTV video you need to restart the program since the frame size changes. The solution is to reboot and make sure the DVD is the first disk mounted on the CD-ROM drive. The kernel will accept DVD sizes until you insert the first 700MB CD in the drive. Another thing that worked around the IDE bug in some kernel revisions was SCSI emulation.
SCSI emulation drifts in and out of functionality depending on the kernel revision.
