I asked whether the HVR-950 would work in mythtv, here a week or two ago 
and received no response. Since then I have picked one up and taken a 
look at the v4l-dvb-kernel site.

I have not started to play with this yet, but one thing you might want 
to check are the names of the modules which get loaded by each of these 
conflicting setups.

Long long ago on this list.... (HAH!, October last year!) one of the 
major problem threads involved getting ivtv and cx88-dvb to play 
nice...they both had a module called tveeprom.ko.  For a while the best 
way to get them working was to rename the ivtv version to 
tveeprom_ivtv.ko. After a while it became possible to use the dvb 
version module with ivtv, and the answer was to delete the ivtv version 
if it existed....Now all of that is ancient history...kernel 2.6.15 and 
ivtv 4.0...

I wonder whether the same sort of thing might be going on. All of these 
units have firmware in eeprom and I would not be surprised to learn that 
there is a tveeprom.ko in the v4l-dvb-kernel source tree. The fix *may* 
be as easy as renaming that to tveeprom_v4l.ko...(but I wouldn't bet on 

If you get a chance over the weekend, let us know what happens.
