[mythtv-users] Tale of two Tuners Hauppauge HVR-1250 Kworld ATSC 115

[Mir Islam]

Hi, I recently added a Hauppauge WintV-HVR-1250 tuner to my MythBuntu
box. I already had Kworld ATSC 115 tuner which has been working fine.
However I can't get the new tuner to work. The tuner is getting
recognized during boot time. But giving an error in initializing
frontend. As per some suggestions on ubuntuforum I added hvr1250.conf
with the content: options cx23885 card=20


Any idea on howto get it to work? Myth backend setup finds Kworld card
only and for mpeg-2 encoder it shows "Failed to Probe" error message.

Thanks
Mir
