Hi folks,

I am trying to get my FlyDVB Trio card working with the trial broadcasts
that are currently underway in South Africa (Johannesburg).

I have got the drivers loaded fine, and used "w_scan" as described on
the wiki to generate an initial tuning file (attached). From there I
used "scan" to construct a channels.conf file (also attached).

However, my problem arises is that there do not seem to be any audio or
video PIDs identified. It is possible that the broadcast is encrypted,
since I see many station names operated by MultiChoice (normally DVB-S
with CA).

I did try using dvbtraffic to see which PIDs were generating the most
data, but entering that as the video PID for an arbitrary station was
unsuccessful. Any ideas what I can try further? Unfortunately, our
"Department of Communications" has not been very communicative about
these trials, so I don't have any more information about how these
stations are being transmitted.

A snippet of dvbtraffic while "tzap RT" was running follows:

1fff    93 p/s    17 kb/s   140 kbit
2000  3311 p/s   607 kb/s  4980 kbit

To my mind, these all seem *way* too low to be meaningful, right?

Is there anything else I can try?

Thanks

Rogan
P.S. Cc: appreciated, but I do read the list via GMANE as well occasionally.
