| Post subject: | pchdtv 5500 problem |
While I have used mythtv for a long time with another distro. I am using knoppmyth and a pchdtv hd-5500 card both for the first time. Here is the problem. I know of at least two strong channels in this area, 3_1 and 3_2 both coming from the same station. When I do the channel scan I see it obtains a lock at least twice if not more. However when it finishes there is only 3_2 in the channel list. I tried manually adding the other one. When I fired up mythtv and go to watch live tv 3_2 displays fine but when I try the other channel it displays partial lock then after that it refuses to display any other channel until I reboot. If it weren't for the fact that both channels are from the same local station and both work just fine when directly hooked up to my hdtv. I would assume it is just a case of poor signal. Am I making some stupid newbie mistake or is there a driver problem or is it signal related? Another question I have is do these 3_1 and 3_2 designations match a specific frequency or is that arbitrary.? |

I had a similar problem with the hd-5500 card when a station that was normally broadcasting was offline one day and I happen to tune to that channel. I could not get it to change to any other channel until I did a reboot as well. luckily I also had a HD3000 card as well and could change cards but nothing could change the channel on the hd-5500 I don't have a resolution but have had the same problem. |

Sorry no resolution here either, but since misery loves company, just wanted to say that I've always had this problem with my HD3000 card. If I accidentally tune it to a marginal station (or if I've rotated my antenna, making a good station marginal) and it doesn't get a lock, it often screws up the card so that no stations are tunable, until I reboot. |

Thanks for the commiseration.  From what you are saying it sounds like the most likely culprit is lack of a strong signal. That seems strange as both stations are from the same source. However one station is broadcasting in higher def than the other, so I assume that could account for the difference.
Thanks again. |

Just an update for anyone with a similar problem. I noticed in the mythtv-setup there was an option to only list channels that were free or words to that effect. Somehow that had gotten checked and once I unchecked that it found both of the channels and tunes them just fine now. I assume that the stream has something in it to tell the decoder it is not for recording, |
