The software encoder (NuppelVideoRecorder) assumes 4:3 input and there's
currently no way to change it via a setting.

If this is the only card you have and you want to force it via a hack to
the source code, you can edit mythtv/libs/libmythtv/NuppelVideoRecorder.cpp
and search for "video_aspect = 1.33333;" in
NuppelVideoRecorder::NuppelVideoRecorder() and change that to
"video_aspect = 1.77777;" to force 16:9 aspect ratio in the .nuv file.

It wouldn't be that hard for someone to add support for an Aspect Ratio
setting for analog capturecards to use for what you're describing.
