Description

The firewire works with test-mpeg2 and files are playable with mplayer, but not vlc. In myth I get a message 2010-09-25 13:30:30.157 ProgramInfo?(2100_20100925133023.mpg), Error: Unknown type, recording width was 0 Looks like myth is finding a PID 2010-09-25 13:30:23.331 RecBase?(16:/dev/video): SetRingBuffer?(0xabd4f0) '/data/mythtv/livetv/2100_20100925133023.mpg' 2010-09-25 13:30:23.331 CreatePATSingleProgram() 2010-09-25 13:30:23.332 PAT in input stream 2010-09-25 13:30:23.332 Program Association Table

It looks like I'm seeing the same issue as http://www.gossamer-threads.com/lists/mythtv/users/420783. Firewire was working for 6 months and recently stopped. Cable box is SA4250HDC.

Here is the output from dvbsnoop dvbsnoop -s ts -tsraw -if test.mpg |grep PID|sort|uniq

PID: 0 (0x0000) [= ISO 13818-1 Program Association Table (PAT)]

Looks like there is no valid PMT in the source stream. We do not support recording or playing naked streams without a PMT.
