Have you looked at the frontend log, perhaps with -v playback?  There 
are other tools you could use to examine the file (vlc, mediainfo) but 
it doesn't sound as if your problems are with faulty or noisy capture.

There are ways of filtering out unwanted streams;  mythutil --help shows 
several tools for mpeg-ts files (which I have never tried) and I 
routinely use a script to do it - but it would be better to get the 
recorder to do that rather than try to fix things later.  There are a 
few options in mythtvsetup.

HP-mini had some good suggestions too, but I won't copy them here.
