I had to do a reinstall of mediaportal and after doing so the tv service is stuttering and the audio is out of sync.

It's almost as though hardware acceleration is not being used and the cpu (P4 3.0gHz) is trying to do the work.

I have tried different decoders but it makes no difference.

Am I missing something obvious here? All of the TV Server settings are the same, in fact I didn't have to change anything after the reinstall, all of the settings were already there.

One other odd thing is last night when I was trying to fix it the TV service wouldn't start, a message box popped up stating that the tv card wasn't available. I have nothing else running that would use the card so not sure what happened there.

DVD's and video's off the hard drive play fine so it's definately the tv card (Nova S Plus).

Have you tested your HA theory? In case your not sure how: change MP>config>general to open MP in windowed mode. I prefer to use Process Explorer for testing operations. Just goto file>use PE instead of Windows task Manager. This will give more accurate details.

Now, open MP in windowed mode & play a file. Alt-Ctrl-Del to open Process Explorer & you should see MP's CPU useage.

It should be around 10-35-odd %. Can vary, but shouldn't really be over that. Is your card for satellite: DVB-S?? If so, I would imagine as it doesn't decode H.264 HD siganls, it should definitely be below that. Otherwise you may have codec issue???

One other thing: you state all your settings were there after your MP reinstall. This says it wasn't a clean install. It may pay to complete another reinstall & totally delete all files from your MP folder location before the reinstall.

You can export your TV channel settings so you don't have to rescan. 'MP TVserver>config' goto 'TV Channels' tab and click export button. This save your channels' list in *.xml format for importing after reinstall/updating. But I wouldn't save these particular settings as you could well imort your problems back.

Finally, you can automate your TVservice startup if failure occurs:

start>run
'services.msc'
scroll to tvservice & click on
click on 'recovery' tab & the options are there for 1st, 2nd & subsequent failures. I have 1st & 2nd set to 'restart the service' with the final one rebooting the PC.
