This is a libmpeg2 feature. It is more optimized for best possible speed 
rather than quality. If you want quality then use ffmpeg for decoding. 

Also it is very likely that anything you save off a dvb device will have 
some errors in it. This can be caused by so many different things you 
can't really do much about it. Most of these are so small that you won't 
even notice they're there unless your're using a really badly behaved 
decoder. Sometimes there are errors and you just have to live with it. 
Probably the best thing you can do about it is to run the captured mpegs 
through a program that removes the broken parts such as projectx.
