[mythtv-users] mjpeg cropping picture

[Dave Pippenger]

I just setup my backend with a DC10+ NTSC and I'm having a simmilar 
issue... In my case the image is cropped from the LHS and displayed on the 
RHS. The interesting part is I can make the effect go away if I switch to 
1x1... unfortunately 1x1 is a bit much for my frontend to decode so I need 
to get running at 2x2 without the image corruption. I have played with the 
overscan/underscan but the corrupted portion of the video just underscans 
in with the video :(  I know a few other people on the list are using the 
DC10+... have any of you seen this problem?
