Hello all,
I've recently setup a mythv system with a single PVR-500, taking input
from a Comcast basic (non-digital) cable feed.
The issue I'm having is that the first tuner on the PVR-500 (tuner0)
will automatically mute it's self when tuning to certain channels. Once
this happens I can't un-mute the card (via ivtvctl -y mute=0 -d
/dev/video0), and have to remove the ivtv module and reload it.
I can it's not just the lower frequency channels ( which I under stand
overlap with the FM radio range) either, it will mute when tuning to
us-cable channel 8 (181.250 MHz), as well as channel 62 (451.250 MHz)
but works fine on 33 (277.250 MHz).
While tuner1 works great on all the channels.
Visually there is not much of a difference as far as quality (other than
some ghosting on channel 8), and the audio sounds perfect when listening
on tuner1.
Reading the archives it seems similar to the thread titled "PVR-500 weak
signal first tuner" however there are no visual or auditory issues.
I've not yet tried the recommendation of adjusting the frequency
manually up or down 20 per that thread, and I'm going to try to do that
this weekend. As well as I'm going to see if I can replace the very old
exterior RG6 line coming in from the demarc as it's quite weathered.
However any input or further testing I could do would be much
appreciated as I'm kinda stumped.
Thanks!
Berant
