I should mention that this happens regardless of whether deinterlace is
turned on for playback, at 640x480 for MPEG4. At least it's more
encouraging than a blank screen with no errors. I'll try other settings
(RTJPeg, different resolutions, etc.)

1. editting backend_settings.txt solved the connection problem. I
thought I'd done that. 2. On an Athlon processor, I get an Illegal
instruction error now. I'm using an ATI TV wonder capture card, and an
ATI Radeon 8500 video card, and Red Hat 8.0.93 with DRI enabled. I have
attached a backtrace from GDB. -Steve

Program received signal SIGILL, Illegal instruction.

Secondly, use the gatos drivers with your video card.
