<span class="postbody">Now, I have this working partially
<br>
<br>
I have a Sky box connected to the s-vid on a PVR-250, and I'm using a USB-UIRT to change the channel on the Sky box.
<br>
<br>
I'm using this <a href="http://www.mythtv.org/wiki/index.php/Script_-_SKY_channel_changer">http://www.mythtv.org/wiki/index.php/Script_-_SKY_channel_changer</a> script to change the channel.
<br>
<br>
When I start watching live tv it only works if the startchan in the db is set to a nonexistant channel. Which is fair enough I think, as mythtv is tuning nothing, the tuning is happening in the Sky box.<br>
<br>
When I change channel, the USB-UIRT does its thing and successfully
changes channel, and the new channel number is entered into the db.
However, this is where live TV stops.
<br>
<br>
If I try to restart live TV, it hangs on a black screen for around a minute, then goes back to the myth home screen.
<br>
<br>
If I manually go into the database and change the startchan back to a nonexistant channel then restart the backend, it works again.
<br>
<br>
Here is what I think is relevant info line from my channels table, one of the sky channels
<br>
<br>
chanid 4304
<br>
channum 106
<br>
freqid 106
<br>
sourceid 4
<br>
callsign SKYON
<br>
name Sky One
<br>
<br>
I used this <a href="http://www.mythtv.org/wiki/index.php/Sky_frequency_numbers">http://www.mythtv.org/wiki/index.php/Sky_frequency_numbers</a> to determine freqids and channums.
<br><br>It looks as if myth is getting confused when it sees a real channel from the db in the startchan, tries to tune it, but there is nothing to do<br>
<br>
Where am I going wrong?</span><br clear="all"><br>-- <br>No, no, you see the rules of language are purely arbitrary stodgy ivory-tower crap we doesn't have to worried aboard because everytime history on you rebendible sausage mountain.
