as I understand it, he wrote that he concatenated files with mencoder.
I would do that the following way:

mencoder file1 file2 -o file.out -oac copy -ovc copy

With that, I did never encounter problems. If the files differ in video 
format/size and/or audio format/rate etc, I encode the single parts into 
the same common denominator and join them later.

The only drawback is that it doesn't work well if there is some audio or 
video missing from one of the files, so they don't get joined that 
nicely. I have no real solution for that a.t.m.
