Some .rec files do not play

Hi
Some of the .rec files produced by my Topfield TF5800 PVR will not play (no video or audio and the progress bar does not move) in VLC 1.1.11. They play fine in mplayer.
I tried the latest nightly build 1.2.0-pre1-20111110-0303 Twoflower with no success.
(These files also won't play in XBMC 10.1 and that forum advised me to try an XBMC nightly with a new version of ffmpeg and this worked. They also mentioned that VLC uses ffmpeg and so this might explain the VLC problem).
Debug messages output @

Any ideas?

I tried that but VLC just reports:
"VLC can't recognize the input's format:
The format of 'file:///M:/test.rec' cannot be detected. Have a look at the log for details"
Messages (verbosity 1) says:
main error: no suitable demux module for `file/avcodec://M:\test.rec'
However this happens for known working .rec files too.
If I reset the Demux module to to Default then it returns to playing the known working .rec files fine.

Does tool called Mediainfo identify those problematic .rec files?

Sorry, I missed the subtitle line the log on first check. You have to remove W:\Toppy\World's Strictest Parents 2011\The Worlds Strictest Parents_110821 not VLC_fixed_problem.txt from that folder. There is a bug in current VLC releases, that will cause stopping issue if you try to playback external subtitle file with TS/M2TS input.

Gah, that wasn't a subtitle file so no idea why it was detected as such. Anyway here's the new log after I moved the problem .rec file into it's own folder:

It seems VLC doesn't find the packets after first ones. Only thing that helps for sure is ProjectX demux and then remux with proper tool, but that is quite nasty if every DVB recording does that.

The problem with reencoding is that you can lose subtitles, not to mention that it's a pain, especially when mplayer and a later build of XBMC with a later FFMPEG) seem to cope OK with it.
What next?

You don't lose subtitles with ProjectX, you can demux them and add them back when you remux.

That all sounds like a heap of work and too time-consuming - it's far easier for me to use mplayer instead of VLC ...
Can't there be a bug filed for VLC?

I can open a ticket for this if you share us one sample file that doesn't play in VLC.
