OK, I'm stumped. I have my HD5000 installed, and after reverting from
2.6.14 to 2.6.13 it's registering the frontend, so Linux is happy.
However, I try to azap or dvbscan and it hangs. I have used the card in
a Windows machine, and it works. I swapped it again today to get all
the pertinent tuning frequencies. Back in Linux I entered one (ESPNHD)
into a channels.conf to test:
ESPNHD:531000000:QAM_256:0:0
[root@localhost szap]# ./azap -r espnhd
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
tuning to 531000000 Hz
video pid 0x0000, audio pid 0x0000

The first try looks like it makes better progress. The next try hangs
earlier in the process.

Also, attempting to do a channel scan in mythtv-setup makes mythtv-setup
hang. Again, I'm stumped! Please find the clue I don't see. I'm able
to decypher this set of lines from the terminal window a little better.
Why would my symbol rate be set to 0? ...and how do I set it?
