[mythtv-users] concatenating recordings?

I may be missing something big here, and be on completely the wrong tack ...

I was under the impression that a recording (at least for those of us 
using DVB) is simply a capture of a broadcast bitstream over a 
period. Thus concatenating two recordings ought to be just a matter 
of joining the two files together :

cat file1 file2 > bigfile

I'd imagine worst case is there's something on the front of the file, 
and so you'd have a bit in the middle that wasn't a valid stream. 
Since the decoder has to cope with dropouts and serious errors, it 
ought to be able to cope and pick up at the next key frame - ie it 
would treat the bit at the join as just a burst of transmission noise.

Or have I missed something ?
