Synopsis:: -

My MP is not very reliable. I can never trust a channel to tune and therefore scheduled recordings are a gamble. (I.e. WAF low)

I have digital channels via DVB-T and satellit channels via CVBS. Recently one of the digital channels (TV4) and one of the satellite channels (TV3) stoped working. TV4 works in WinTV2000 and the other satellite channels works via the same connector (CVBS).

Occationally other channels don't work, but that is intermittent and will often work by shifting to another channel and back again.

The enclosed log files covers the following actions:

Start MP
Enter TV (Starts with a working TV1 (DVB-T) in windowed mode.)
Going to full screen.
Going to TV4 (DVB-T), gets black screen (as always!)
Going to TV6 (CVBS), gets black screen (works normally, but not this time)
Going to TV8 (CVBS), works
Going to TV3 (CVBS), gets black screen (as always!)
Stop MP

In the log I can see that MP thinks TV3 is digital. But in MediaPortal Setup it is defined as 250002/3 (which means CVBS external STB channel 3).

Also it looks like DX9 is not used. Why? The Nvida 6150 should support it and the setup is set to use it.

Not shown in this log is that the TV picture quite often freezes after channel changes, within 10 sec or so. It will normally work again if I turn TS off.

I'm also surprised to see the No signal message now and then for the CVBS-input. It always has a signal from the STB.

I'm now running a clean 0.2.1.0 (with no SVN) but I had the same problem with a clean 0.2.0.4.

Would love to get a solution to this as it has bothered me for a while.
