I think you may be right now. > Can you kill the mythbackend and bring up two captures in two mplayer > commanlines, one on from the HVR-1600 and one from the PVR-150? > > $ mplayer /dev/video0 -cache 8192 > (another terminal window) > $ mplayer /dev/video1 -cache 8192 Doing this I see two mplayer windows, both displayed to the correct widths. I tried to take snapshots but only one of the windows would capture. The other always came out black (only the snapshot, however - the 150 window). > MythTV will leave your cards set at 480x480.

I did this and then double checked if MythTV was still displaying incorrectly. It does. BTW, the ",pixelformat=MPEG" was not recognized by the version of v4l2-ctl I have, which is from the latest ivtv release (1.0.3) from Linuxtv.org (http://linuxtv.org/hg/v4l-dvb/archive/tip.tar.bz2) > Hmmm.

I have a cold and can't think too clearly right now. Me too, or rather I'm just getting over one. Nasty bug goin' 'round. I don't know how to turn on the debug stuff, but then is it necessary if we're confident this is MythTV and not the driver? Should I take this over to the MythTV Dev list? If you still need the debug output, just point me to the info. I know it has to do with the parm option listed in the modinfo, I'm just not sure how to set this (in modprobe.conf?) Thanks for the help Andy. -- Michael J.
