for matched aspect playback, its probably better to change the capture 
setting to match the output resolution of the STB. Then you won't lose 
any quality.
 From the sound of it that is 576p (1024x768) or for a more modern box 
720p. My penny is on the latter. If your capture device can do it set it 
for 1280720.
Transcode to any quality less if required.
