VDR uses the (fixed) "pseudo" PMT pid 0x0084, which is 132.
This was taken from some patch that implemented PAT/PMT handling
(don't remember which one it was, maybe it was even the code from
reel multimedia - not sure if I've missed mentioning that in the
CONTRIBUTORS file).

Anyway, I was already wondering if simply using some fixed PMT
pid was such a good idea. What if some other stream uses exactly
that pid? Apparently this is the case in this example.

So I guess it will be necessary to first collect all pids and then
check whether the default pseudo PMT pid is still free, and if
not, incresase it until a free one is found...
