To: mythtv-users at mythtv.org


When I do an OTA channel scan in the backend setup, it detects all the
channels I'd expect to see.  I close the backend setup and run
mythfilldatabase and startup the front-end.  I see the channels listed
in the program guide.  When I try to tune one of the OTA channels, the
system freezes.  I have to do a ctrl+alt+delete and restart to get my
system back.

I had the MythBuntu/Hauppauge 1600/OTA working about six months ago.
Since then I tried using the digital inputs on the card to pick up
clear QAM programming Comcast.  Now I'm trying to get back to get back
to OTA signal on the digital portion of the card (unsuccessfully).
Since it worked at one time, I assume there is a config setting I'm
not setting correctly.

The signal strength from the antenna is fine.  I attached a digital
converter box and the channels came in very clear.  The converter box
showed the signal strength between 84% - 94%.

I noticed I posted more as a statement and not as a question.  Does
anybody know what might be causing my problem?
