Since i have upgraded my tv server to 1.10 RC 1 i get the really helpfull error "unknown error occured". This happens on the tv server when I want to wacht the channel I watched the last time. For example, I am watching rtl4, then stop watching. And one minute later i want to see rtl4 again -> "Unknown error occored". When i tune in to another channel and back to rtl4 no problem.


Edit: Removed logs, they are now posted as files.

This sounds very much like the same error that has been seen with ATSC cards on Windows 7. In this thread:
https://forum.team-mediaportal.com/...d-watch-consecutive-shows-same-channel-76455/

a patch is posted by whurlston, which solved my issues for ATSC/QAM. You could try to make similar changes to the DVBC code.

Please post all logs as attachments instead of inline. You can use the Mediaportal logs collector for that.

I have reproduced the problem and here are the complete log files.

I went ahead and applied the fixes from the ATSC thread to the DVBC code and compiled the dll. insan3, can you test the attached TVLibrary.dll?

Stop TVServer, navigate to C:\Program Files\Team Mediaportal\TVServer, rename TVLibrary.dll to something like TVLibrary.dll.orig and copy the attached TVLibrary to the same directory.

I don't see why these modifications should fix this. But please try. The problem is a tune to the transponder on which your card is already tuned can not be handled. That returns error 0x1. I once made a hack for Vista TV Pack to ignore this 0x1 error result on tune, that could be tried since it worked then. Please remind: That is not a solution, only a hack.

Not supported OS hence setting this specific thread as "no bug".

I also tried to ignore the 0x1 error for ATSC when I first ran into this problem and it would not work. According to previous reports it did work for the MP 1.0.2 code and Vista TV Pack.

Jay,
I tried the dll from you post and it didn't work. I know 2008R2 is not supported but it has worked in the past with no problem. 2008R2 is just a version of win7 without BDA support. And i installed the BDA support using a BDA package.
