Channels no longer working (1 Viewer)

Hi,
All of a sudden, some of my tv channels have stopped working.
My setup is TVServer on a dedicated server, and tv-clients in various rooms.
It is IPTV.

I have attached some logs, from when I switch to a channel, that doesn't work (BBC Entertainment).
Is it possible, that they are suddenly encrypted (or something) from my provider? Is there a way I can tell?

Media Portal simply reverts to the last shown image, from the previous channel, which is then displayed while subtitles run from the new channel. I can switch to a working channel while this is happening.
Also, while this is going on, the TSWriter log, fills with lines like this:

20-12-2012 15:34:35.280 Recorder:Pid 200 Continuity error... c ( prev a ) - bad signal?
20-12-2012 15:34:35.281 Recorder:Pid 200 Continuity error... 3 ( prev 1 ) - bad signal?
20-12-2012 15:34:35.281 Recorder:Pid 200 Continuity error... a ( prev 8 ) - bad signal?
20-12-2012 15:34:35.281 Recorder:Pid 200 Continuity error... f ( prev d ) - bad signal?
20-12-2012 15:34:35.281 Recorder:Pid 200 Continuity error... 6 ( prev 4 ) - bad signal?
20-12-2012 15:34:35.281 Recorder:Pid 200 Continuity error... c ( prev a ) - bad signal?

The TV Server would report if the channel was scrambled.

Is your hard disk set to switch off after 20 minutes?
Try turning the power saving feature off or increase the time to 60 minutes, then try the channels again.

Nope, it has been running fine, for ages. It is ALWAYS the same channels this affect, and I started noticing it about 14 days ago.

I tried opening the channel with VLC, on the server machine, and the image is blurry, but showing. VERY BLURRY.
Trying to view codec info, VLC crashed.

Are there any analysis tools I can run, on the stream, to see what might be wrong?
It doesn't list as scrambled or encrypted, anywhere I look.
