I have tried specifying a tuner type in modeprob.d/options and this has given me limited success (options cx88xx tuner=64). I have been able to get the channel scan to work doing this, but so far no video capture. I am not sure what the correct tuner is or how I can now capture video to see if it is working. I have tried the watch tv option and catpure video on mythtv tv, but the live TV times out and the recorded video is just snow, so something is still not quite right with the setup.
Is there a simple way to dump the digitial video from a specified channnel to a file and play it with mplayer or something?
Hope someone can help fix this tunner issue. (see my previous post for more details).

tuner. The TAPE-H091F-MK3 and TAPE-Hxxx data sheets I have say this
about the analog ranges:
Low : 55.25 - 157.25 MHz
Mid : 163.25 - 439.25 MHz
High: 445.25 - 801.25 MHz
FM: 88.00 - 108.00 MHz
The step size is programmable: 31.25 kHz, 50.00 kHz, 62.50 kHz, ...
With a control byte of 0x8e (as in the tuner_fm1236_mk3_params), you're
programming a step size of 62.50 kHz.
Of course this is an analog M/N system tuner with FM radio. I suspect
this isn't the tuner you're looking for, for Digital TV.

Andy
