I don't think this is the optimal way to go. Transport streams from DVB sources
are typically created in professional environment and are supposed to work fine
with standards-compliant STBs.

Instead I'd suggest to investigate further - does the problem happen with other
DVB sources, other STBs etc? For the affected source, could you please capture
TCPdump output for at least two seconds on some Unix machine and check for
irregularities (gaps) in timestamps?

With kind regards,
