The fix for mantis 3171 (tuning a channel sometimes results in "no audio video video detected") breaks support for analog (including) HDPVR and hybrid cards. Scanning still works, but viewing times out waiting for video and audio even though audio and video start events are logged.

I can reproduce this consistently on my machine. Satellite works fine.
I've created a patch that solves the problem for me on all formats that I can test (DVB-T, DVB-S, analog TV, FM radio, hybrid). I'm unable to test IP-TV.

Note: this is the first issue that I've raised. I'm not sure what to put in the "docs req'd" field.

h4. Steps to Reproduce
Attempt to tune a channel on a hybrid card.
Scanning works, timeshifting does not.
