The aspect ratio is written to the new file in NuppelVideoRecorder::WriteHeader()
which is called only 5 lines below where the call to NVR::SetVideoAspect()
and nothing in between those two modifies the aspect so it should be writing out
the correct aspect ratio. You could try adding a similar VERBOSE line inside
NuppelVideoRecorder::WriteHeader() to verify the aspect ratio being written to
the file is the right one, but I don't see how it could be changed if you are
seeing it correct when we call NVR::SetVideoAspect().

Are you sure that's not the dsmyth or whatever decoder you are using since
these .nuv files are Myth's enhanced nuppel format?

Can you past the nuvinfo output here?
