In TV server config:
After previewing a channel, If I don't restart tvservice, I get "cannot start graph" error if I try to preview other channel. If I restart the tv service it can preview (one) channel agen.

In MP:
After switching to "bad" channels (scrambled, or scrambled video, or no video) I get "cannot start graph" error. Which is again gone if I restart the service. Switching between "normal" channels works fine.

DVBViewer technisat edition and DVB Dream have no problem switching between channels, including "bad" ones.

Thank you in advance,

Could not find any post on the subject using forum search. Sorry if I have missed one.

Same thing here, and there are a few posts on the forum which suggest the same problem, no reply so far.
It seems to happen really only on SkyStar2 HD cards, after a "TwinHan DiSEqC cmd:4 0 0 0 E0 10 38 FE 0 0 0 0 0 0 0 0 failed 0x8007001F" in TV server log, after that it's always "Waiting for PMT" and it reaches the timeout asking to increase the default value of 10s, which of course does not solve anything.
I used on the same software/hardware setup of MP a SkyStar2 (not HD) before upgrading to the HD version, never ever had such a problem, was working flawlessly for more then 5-6 months, it was not using the BDA driver, the new HD one is using the BDA driver, maybe this is the prob., don't know really.

BTW, my signal/quality is ~90/90 (in some posts someone suggested that low signal/quality could cause probs.) and the same hardware setup works like a dream in DVBViewer and DVBDream.

Anyway, I would really like to get some feedback from some MP developer or someone more technical, I myself am a developer and did debug MP in a few instances already (and submitted patches once), could someone at least tell me where and to what to take a look ?

Thnx in advance,
