Hi! I've been experiencing problems with some TDT-TV channels since 2 days ago. When I try to turn TV on, I often get a message saying "No signal", and no image or sound are displayed. It happens about 75% of the times. After several tests, I realised it happens with the channels transmitting in the same frequency (842 MHz).

I've reinstalled MP, and even tried a different DB (I'm using MySQL 5.1, but SQL Server Express 2005 results in the same problem).

A piece of the TV log is here shown:

Maybe it's a problem related to new channels appearing in the spectrum. I'm in Cordoba, Spain. Please, any help? I'm getting crazy. Thanks.

More info: I installed the TV card software and updated the drivers. No way. There is no problem when using the TV card software (WinTV), but through MP (or directly using TV Server configuration program) it is often unable to get the signal. Thus, it is clearly a TV Server problem. The channels involved are: laSexta, Cuatro and CNN+ (in Cordoba, Spain). Any ideas? Thx.

 

[Eddie73]

I think I've solved the problem. I noticed it also happened when using the TV software, but less frequently. So, the problem was not related to MP, but the TV card itself.

In the end, it seemed to be a TV signal problem. I've installed an amplifier and, since then, no problem. Thx for reading.

Good for you it got solved.
By commenting, you might have less the feeling you were talking to yourself...

 

[Eddie73]

Ha ha! Of course I've had that feeling. However, I just wanted to post the solution to my problem, so that anyone could avoid wasting his time trying different things as I did. I have no free time to play with MP, so I can't help many people here. But, if I have a problem and I discover the solution, I don't mind to "talk to myself". Maybe, somebody is listening elsewhere...
