Hi,<BR>
<BR>
I've been reading this thread with some interest now, since I'm having quite "interesting" problems with MythTV related to IPTV (see this thread: <A HREF="http://www.mythtv.org/pipermail/mythtv-users/2010-December/305163.html">http://www.mythtv.org/pipermail/mythtv-users/2010-December/305163.html</A>)<BR>
<BR>
The basic problem right now, before starting to mess with the beast again tonight is that "the first channel works" (!) when tuning in to IPTV. When changing to another channel on the same IPTV provider, it gives me the ugly "Error opening program jump file" or similar error.<BR>
<BR>
What I did some days ago was to change the networking so that my mythtv backend has a "real" IP address (non-NAT:ed), but this hasn't helped unfortunately.<BR>
<BR>
Tonight, I also tried messing around with the .m3u as described below (using rtp:// instead of udp:// which I was previously having, but NOT with the @ sign which MythTV doesn't seem to like), but it didn't work. I changed back - it still doesn't work. Now it doesn't even tune a single IPTV channel... :-/<BR>
<BR>
The -v channel log doesn't give me that much, unfortunately. I did some packet capturing (using tcpdump) and it seems to start subscribing to the multicast stream. It just fails to show it in mythtv. :-(<BR>
<BR>
How on earth can this be so hard to get working? With VLC or mplayer, it works immediately, with the same URL (but after insering an @ sign like this: udp://@<A HREF="http://233.60.167.19:1111">233.60.167.19:1111</A><BR>
<BR>
With MythTV, this should be udp://<A HREF="http://233.60.167.19:1111">233.60.167.19:1111</A> but not even this works any more. I've seriously considered buying a DVB-T card, just to get around this, but it feels... stupid. Blargh! Any ideas, from anyone, are highly appreciated. TIA.<BR>
<BR>
Best regards,<BR>

I feel your pain.<BR>
<BR>
The way Mythtv works (to my understanding which is still limited), it spools the stream to a file then the internal player plays the file. This gives you the ability to pause and rewind live tv. I think this is the jump file the error is referring to. You may want to check the livetv directory / group to see if the file is being created or is empty.<BR>

Guru's can jump in here and correct me if I'm wrong.<BR>
