Can't stop and start tv in mediaportal (1 Viewer)

[dhanjel]

Hello guys, I have some problems with the tv-server and/or the clientplugin in media portal that I need some input on from you before looking any deeper on it.

If i from a fresh reboot enters "TV" in mediaportal, everything is ok and working perfectly fine. But if I set "TV ON" to off and back to on, I get an error that says "Unable to start timeshifting. An unknown error has occurred".

When that happens, I have to restart the tv-service and re-enter media portal to be able to watch tv again.

The only relevant information I can find in the logs are:

Has any of you encountered this?

Vista 32bit, RC3 (even tested latest SVN), Twinhan DVB-C card.

Any help or suggestions on how to move forward on this are appreciated.
