Hi,

few months ago on this transponder was nearly 30% of null PID packets
broadcasted, but now it seems to be much better (less than 1Mbps). Also
multiplexing of this transponder was not equal within time - there was
chunks of packets of PlanetHD multiplexed with chunks of other SD
channels mixed packets. Maybe the buffers for USB are not big enough to
memorize such chunks? But I didn't done measuring for some months, so
the situation may be different now.

You can see bitrates of this transponder at
http://www.digitalbitrate.com/dtv.php?mux=11817&pid=5410&live=70&lang=en .

The bitrate of this channel is nothing special, with maximum about 11
Mbps, the peak of 20.2Mbps at 22.5. was maybe a joke.
