Yeah, this is a playback issue, right?  Since the ConvertX doesn't 
capture at 1024x768...

The bitrate control slider doesn't work?  What do you have it set to? Have
you changed the bitrate for all of the profiles in the "USB Mpeg-4
Encoder" group in the Recording Profiles menu?

Probably a hotplug problem...  Are there messages in your /var/log/syslog
on startup that indicate a problem loading the driver or firmware or
anything?  I haven't played with Knoppmyth so I can't vouch for it being
configured correctly.

are you running into?

MythTV only supports MPEG4 capture on the ConvertX.  -Nathan
