Thanks Steven for all the support,

Now I got the master slave to work and I can scan the local FOX channel with
azap

tridentsx@tridentsx-P5K-E:~/.kde/share/apps/kaffeine$ azap FOX
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
tuning to 599028615 Hz
video pid 0x0031, audio pid 0x0034
status 01 | signal 0000 | snr 0000 | ber 00000000 | unc 0000ca8b |

FE_HAS_LOCK
status 1f | signal 8d3f | snr 00c1 | ber 00000000 | unc 00000000 |
FE_HAS_LOCK

However when I try to view or scan channels in mplayer or kaffeine it can't
find them and there 
are some timeouts Similar to the ones I got in scan utility. 

kaffeine(5476) DvbScanFilter::timerEvent: timeout while reading section;
type = 3 pid = 8187 
kaffeine(5476) DvbScanFilter::timerEvent: timeout while reading section;
type = 0 pid = 0 
kaffeine(5476) DvbScanFilter::timerEvent: timeout while reading section;
type = 3 pid = 8187 

Playing dvb://.

dvb_streaming_read, attempt N. 1 failed with errno 0 when reading 2048 bytes
dvb_streaming_read, return 0 bytes
Failed to recognize file format.

When I use the scan tool I get the following for every channel that I can
get a lock on in azap

>>> tune to: 473028615:8VSB
WARNING: filter timeout pid 0x0000
WARNING: filter timeout pid 0x1ffb


Below is a kernel  trace at the same time. It seems the tuning is successful
still no channels are output at the end of scan.

You are very welcome, thank you.

We generally recommend Linux users purchase cards that are already supported
(or semi supported), such as the HVR2250. If you're keen enough to tackle
adding support for a new board then that's great news, but very few people
usually have experience with hardware not yet supported.

The channels.conf is capable of support digital cable and ATSC, simply
change the modulation scheme and your target frequency and try again.

A quick google for an equivalent ATSC channels.conf provides a lot of useful
information.

Create your channels.conf to match your target frequencies in Hz and use
azap to debug.

Eg.

KPAX-CW:177028615:8VSB:65:68:2
