Hi,
I've been trolling through these threads for a couple weeks now trying to get my Live TV to be clear. I've tried many different suggestions from different posts (change codecs, change dll, change tsreader.ax versions, etc) to no avail. Then I happened upon a post mentioning trying VMR9 instead of EVR.
At first I figured since I'm running Windows7 that using VMR9 would only degrade the video quality (otherwise why would they have made EVR at all?). But I decided to try it. And to my surprise it actually cleared up all of the video stutter.

My question is this, what is the big difference between VMR9 and EVR? When using VMR9 I was dropping frames left right and center, but using VMR9 there is no dropped frames.

And also, is there somewhere that explains the Shift+1 graph? I understand some of it, but not all of it.

Anyways, thanks in advance (btw I love Mediaportal).

Rob

Hi rspierenburg

This is also a question I would appreciate to get an explanation of.
I am having the same issues, and VMR9 seems to fix it, but this of course gives some other issues as VMR9 is not supported on W7. If VMR9 gives a better and more smooth playback why is it not supported?

Best regards
Martin

got the same issue, also on a Ion machine.

Using EVR i get dropped frames (MS DTV, ffdshow).
If i switch to VMR9 i get perfect playback (similar quality to sky+).

However, using VMR9 i seem to lose hardware acceleration for my non-live tv stuff.

Thanks for the tip, I'll check it out, but I don't think its the cause of all the dropped frames. So the question remains, whats the difference between evr and vmr9, and why does vmr9 act so much better than the recommened evr? And is there somewhere I can learn about the shift+1 graph and what it means?
