[mythtv-users] Problems with recording from one channel of IPTV...

Sun Jul 26 23:48:33 UTC 2009

I have an odd problem. One channel (and only one channel) isn't
working with my IPTV setup.

The M3U file part looks like this (it's channel 71 - TLC that's the
problem, channel 9 - NBC Boston, is working just fine.):
#EXTINF:0,9 - NBC Boston
#EXTMYTHTV:xmltvid=I9.28459673.microsoft.com
udp://239.255.0.9:9400
#EXTINF:0,71 - TLC
#EXTMYTHTV:xmltvid=I71.206570750.microsoft.com
udp://239.255.0.51:9404

There is a stream on both IP:port addresses, which I can watch on the
server using VLC or MPlayer without issue.

The Database "Channel" table entries for the same representative
channels look like this:
chanid	channum	freqid	sourceid	callsign	name	icon	finetune	videofilters	xmltvid	recpriority	contrast	brightness	colour	hue	tvformat	commfree	visible	outputfilters	useonairguide	mplexid	serviceid	atscsrcid	tmoffset	atsc_major_chan	atsc_minor_chan	last_record	default_authority	commmethod
2009	9	 	2	NBC Boston	NBC Boston	 	0	
	I9.28459673.microsoft.com	0	32768	32768	32768	32768	Default	0	1	
	0	0	0	NULL	0	0	0	2009-07-25 18:59:31	 	-1
2244	71	 	2	TLC	The Learning Channel	 	0	
	I71.206570750.microsoft.com	0	32768	32768	32768	32768	Default	0	1	
	0	0	0	NULL	0	0	0	2009-07-26 14:59:31	 	-1

So everything should be working fine. But when recording from that
channel, I get the following (-v recording):

are worrying me, but I can't see what's wrong.

In contrast, a successful recording reads:

Can anyone see what I've missed? Is there anything else I need to provide?
