I need to connect 960H camera to A20's TV-IN interface.
960H is PAL-like standart with extenden row width (960 vs 720 in PAL).
If I open /dev/video1 to streaming PAL-signal I see horizontaly flattened
frames.
To open /dev/video1 to streaming 960H-signaI made some patches in tvd
driver:

}
After that TVD sends me 960x576 pxl frames. But left part of frame - is
flattened frame, right 1/4 is garbage.
There are any ideas to solve this problem?
