I don't think you can get rid of Line 21 filter short from unregistering it. I don't think it affects performance so you can probably ignore it.
You should download DXVA Checker (I don't have a link handy). It will check you video card and tell you what it is able to decode using hardware instead of software.
I haven't checked recently but I think my numbers are usually around 15% CPU usage when watching live TV. I'm on a ATI 4850 btw.
I know that MPC filter is able to take advantage of DXVA so the numbers should also be lower. That is only true though if you have everything in order to use DXVA.
Things that affect DXVA could be video driver, directx version, software config...
Like WileE said, I think I also had issues with MPC and the HD-PVR. I think that's when I was getting green flickers or something weird like that.
I typically try to use FFDShow with DXVA or PowerDVD decoder. For me SAF has always worked pretty well for me so I tend to use his "pack".
I also found that I had better success with Win7 32 bit over 64. I loose a bit of RAM but codecs are much more stable on 32 bit.

I guess though if you have good results with MS filters then great. I just prefer not to use their codecs on principle

I now have the Microsoft DTV codec in use now. For the 30 minutes it's been running pretty good! around 40% total cpu; MP around 15%. Shift-1 lines are pretty flat. I show ~750 dropped frames over 120,000 frames drawn. Not bad. Best I've experience I think.

The graphc show a Line 21 filter between the MS codec and the evr. I think this is for subtitles. Anyway to get rid of this; I never use subtitles. Not sure if it adds any load or concern. I still have TME installed. Should I uninstall it?

Wow, great results. and thanks for the awsome advice.

Cool, Im glad its working better. The new video card should show even more improvement.

As far as TME is concerned, I removed it because the Arcsoft splitter was causing issues playing H264 movies (nothing to do with Live TV.) If you have no issues there is no need to remove it. On the flip side though, if you dont use it then best to remove it

Im not sure about the Line 21 filter. I will check my graph sometime to see if it shows up...

Very true, but I have found specific codecs that play certain content really well and I have stuck with them. The guide that BMan came up with was a very good starting point for me. The codecs I use are...

TV
- MPEG-2 FFDShow
- H264 Microsoft DTV
- Audio FFDShow
- Default Audio Renderer

Movies
- MPEG-2 FFDShow
- H264 MPC Video Codec
- Audio FFDShow
- Default Audio Renderer

The only other settings I made is pushing FFDShow to the top of the MPEG-2 Video priority.

I also agree about the Microsoft codec I always used the Cyberlink 9 or 10 codec, but after this last build (which is Win 7 Ultimate x64 w/SP1) the Microsoft codec has performed real well and I havent installed the Cyberlink software. (Less is more I guess.)

Thats good info about the Line 21 filter, I dont know that I have ever came across it before.

Tv seems to work well now except that I specified ffdshow audio but the graph shows MPC-MPA Decoder. Is this a codec merit problem? How would I correct that?

On the video side I tried a number of videos and I can't seem to play .m4v; message is that the video codec is AVC and audio codec is AAC version 4LC. I tried both MPC and Microsoft DTV.

Here are my codec settings:

TV
- MPEG-2 FFDShow Video Decoder
- H264 Microsoft DTV Video Decoder
- Audio FFDShow Audio Decoder
- Default DirectSound Device

Movies
- MPEG-2 FFDShow Video Decoder
- H264 MPC Video Decoder
- Audio FFDShow Audio Decoder
- Default DirectSound Device

If you can't play .m4v files I would say that it's a splitter issue and not a codec issue.
in the MP settings you only specify decoder codecs (if that's what they are called)
Basically MPC or M DTV expect the data to be decompressed from divx or mp4 or what ever the case may be.

Exactly,
This is where the Arcsoft splitter caused me issues.

Andy, just for fun uninstall TME and see if that clears up the issue.

That's exactly what I have just been doing ;-) Didn't work :-( Same result. I unregistered all the AS codec etc. and then uninstalled all of the software and deleted remnant folders.

I need a crash course on how to setup splitters or at least identify which splitters are in play. Ugh!

If you clean your system of all other software (Cyberlink, FFDShow, Arcsoft, etc..) you might try SJeffrey's suggestion and try SAF? He said it works well with his setup (HD-PVR, Colossus, etc...)

Solved!

Now I know what a splitter problem looks like ;-) All I had to do was read our wiki... I installed the Haali Media Splitter (also known as Matroska Splitter) and that, as they say, was that. Done and done. Tv, video, dvd all working with dxva where available.

Thanks guys for your hints and advice. I really appreciate the help this community provides!

hello,

new MediaPortal user here, just installed 1.2 beta yesterday, and have run into a couple of problems that hopefully you guys can help with.

1) I'm trying to set up tv server, but when I hit "preview" I only get a static image. Is this normal? Also, no sound. I'm using component cables, and the rca for sound.
2) Frequently, I get "Preview failed:NoPmtFound", and it doesn't work.
3) In MediaPortal, I have to be careful not to bring up the context menu when watching tv or else the whole program becomes unresponsive to input (mouse and keyboard), although the picture still works. Only way to exit is to bring up task manager and kill the MediaPortal process.
