Technisat HD5000 DVB (HDTV) card registers, but hangs


OK, I'm stumped. I'm building a mythtv machine. I have a Happauge 500MCE NTSC card working well. I'm using x86_64. 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 use the dvb-apps azap or dvbscan and it hangs. It also hangs when trying access it in mythtv, either in mythtv-setup doing a channel scan, or just trying to watch something on it. I have used the card in a Windows machine, and it works. I swapped it again today to get all the pertinent tuning frequencies. I entered one (ESPNHD) into a channels.conf to test:
Code:
ESPNHD:531000000:QAM_256:0:0
Code:
[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.

I know this sounds like a question for mythtv or DVB card types, but I figured the debugging information might make sense to someone here. Again, I'm stumped! Please find the clue I don't see

I'm able to decypher this set of lines a little. Why would my symbol rate be set to 0? ...and how do I fix it?
