[mythtv-users] PVR-500 Only one tuner works

Fri Oct 21 14:34:27 EDT 2005

Peter,

Yes.. The problem is with the kernel tveeprom being used instead of
ivtv's version. So quite simply...

- If you recompile your kernel, the tveeprom (ivtv version) will be
overwritten with the kernel version and hence you will need to
recompile ivtv AFTER recompiling your kernel.
- If you dont recompile your kernel and simply install ivtv. You
shouldn't have a problem.

Things should work, but just incase they don't patch the source and
try again. The patch fixes radio on the PVR500
(http://www.gossamer-threads.com/lists/engine?do=post_attachment;postatt_id=1203;list=ivtv).

Regards,
~Danesh
