Hi Patrick,

Actually, I think you may well be right. Our cell networks are trialling 
(or even deploying) DVB-H, and the content is provided by MultiChoice. 
Unfortunately (for me) that content is almost definitely encrypted.

I guess I might have to retry w_scan to see if it picks up any other 
frequencies that might have the real DVB-T signals on them. And maybe 
improve my antennae - I am currently using a Technisat DigiFlex TT2, 
which is just sitting on my desk.

I am attaching the results of "dvbsnoop -s pidscan", as well as a longer 
capture of dvbtraffic (using "dvbtraffic | tee dvbtraffic.txt", then 
Ctrl-C after 6-7 seconds).

Thanks for your help.

Regards,

Rogan
