<div dir="ltr"><div><div><div><div><div><div><div><div>Greetings,<br><br></div> I did search the list archives, and found 1 recent post (jul 20 this year, subject 'Locked') wherein the user was complaining about mythtv not scanning/tuning-in their connected dvd player - I can only guess I'm seeing the same thing here, but I can probably explain the situation better ;). My backend server setup has 2 x dvb-t cards and the single PVR-150 card. This latter card has only one connection - an RF patch cable between the tuner TV ant in & the RF out socket on an aust-star sat paytv box (which I know is modulating on UHF channel 69 of the old .au frequency table). I have an IR blaster all setup to flip channels on the satbox etc etc, and this all worked a treat by just setting up manual record times/rules for that card in mythtv. There is some picture quality degradation using this route, but it's not -that- bad and still quite watchable.. <br>
<br>...that system was running Debian 6 and in mythtv-setup' you could setup the card as per normal, tell it 'no grabber', connect your RF patch-cable and turn on your vcr/dvd/paytv device, scan for channels, and it'd flip thru the entire (australian here) channel set one at a time (status - No Lock) until it found the channel/frequency the device is modulating on (signal level would jump up & status to 'Locked')., this would give me one channel (which is set as the starting channel) -- worked a treat, and this is the channel 'scanning' that OP was talking about me thinks...then I updated the motherboard, clean install of Debian 7.1 and went to setup the backend fresh, and...<br>
</div><br></div>... now, the same process sees the tuning status proclaiming 'Locked' for the entire frequency/channel set, as it speed-skips through all 50+ channels in 2seconds without pausing/ever seeing -any- signal level ; increasing the tuning timeout etc has no effect. So I decided to check with ivtv-utils, just incase the card had coincidentally died..<br>
<br></div>... issuing 'ivtv-tune -t australia -c 69' returns '/dev/video0 814.250MHz (Signal found)' and if I follow on with 'cat /dev/video0 &>test.mpg' , I get exactly what I expect when replayed with mplayer ; a slightly degraded mpeg capture with audio all as it should be ; so the card is working fine it seems (even to the point of -not- returning 'Signal found' when switching to known vacant channels)....<br>
<br></div>..so, I cross checked a couple of other linux tv apps ; xawtv I can definitely vouch -did- work fine with the pvr-150 I have here (it's type 26559 with FM1216 ME MK3 tuner), but now pretty much mimics the results I get in mythtv...ie; no signal detected on any channel, tvtime refuses to talk to the card at all (incorrect ioctl for device?), so I suspect this problem is not entirely mythtv's fault (if at all). <br>
<br></div>My query is, what should I do about this? Abandon the pvr-150 and get different hardware? If not only mythtv but also the other apps mentioned have seemingly lost the ability to manipulate the card's tuner, where would I look for such a bug and/or report it?<br>
</div><div>Any help/clues/comments appreciated.<br><br></div>Apologies for creating a new thread about this ; couldn't figure out how to reply to the original...<br><br></div>Cheers<br><div><div><div><br><br><br><br></div>
