On the outer TS layer, you can check for TS packet structure ("skipping
bytes to sync on next TS packet") and TS discontinuity, thats probably
all. However this gives quite good hints on data loss and buffer overruns.
On PES layer, there's not much to check, and everything below PES layer
is encoding specific and would require mpeg2 / mpeg-audio / ac3 / h264
specific scans, that are more complicated.
Also, I wouldn't be surprised if there are errors close to the beginning
/ ending of a recording, that you may have to ignore.
Cheers,
Udo
