I can't offer a solution to the original problem, but at least I can explain
briefly what's going on -
DVB is transmitting over the air, and you'd be doing very well to get 100%
of the TS packets. I suspect the OP had a moment of less than perfect
reception at that point - hence a missing packet.

Transcode and other mpeg utilities generally expect a perfect mpeg stream.
We're not able to supply one unless you convert the TS to mpeg with a
utility that can cater for unreliable input.

It's worse if you demultiplex the stream into separate audio and video
streams before transcoding - a loss of a single audio frame can play havoc
with a/v synchronisation.
