Deinterlace is Unstable (1 Viewer)

MediaPortal Version: V1.1 Alpha
Windows Version: Vista SP1
CPU Type: Core 2 Duo E6700
Memory: 2GB
Motherboard: GA-73PVM-S2H
Video Card: nForce 610i
Video Card Driver: Latest
1. TV Card: AverTV Volar Black HD
1. TV Card Type: DVB-T
MPEG2 Video Codec: MPC (Gabset)
h.264 Video Codec: CoreAVC
TV - HTPC Connection: RGB

I have recently installed MP to watch live TV using H.264 DVB-T stream. For some reason I always see interlaced picture artifacts no matter what codec (CoreAVC, FFDShow) or deinterlace method (Bob, etc...) I use.
I see no interlaced artifact when I use other players (VLC or AverTV)

I once changed the MPEG-2 decoder deinterlace method to Bob and it seemed to solve the problem for a few minutes only but I couldn't reproduce it since. I am not sure why it worked since the DVB-T stream is encoded with H. 264. When I look at GraphEdit I see that the MPEG-2 decoder is open but not connected to any other filter (Maybe the tsreader is using somehow the MPEG-2 decoder for the MPEG-2 transport stream?)

This is what I tried:
1. Changing codecs and deinterlace methods.
2. Updating my nVidia driver.
3. Changing rendering mode (EVR/VMR9).


All suggestions are welcome!

1. Find your native screen resolution.
2. Use Nvidia PowerDVD 7 or 8.

I use my native resolution.
What is nVidia powerDVD? I tried installing powerDVD (7 and 9) but its h.264 decoder cannot be used in mediaportal.

I also tried SAF but its h.264 decoder didn't work for me at all.

I have no problem playing any other files in any other programs (VMC, XBMC).

PowerDVD 7 or 8 works together with mediaportal.

PDVD8 deinterlacing is working but the picture does not look so good...

After some searching it appears that there is a bug in the TsReader in H.264 DVB streams. See following threads:
https://forum.team-mediaportal.com/482667-post10.html
CoreCodec Community Forum • View topic - CoreAVC + H.264 + TsReader

It also seems that it's not going to be fixed soon... So I guess there are 3 options:
1. Find old versions of MP and CoreAVC which does work with H.264 DVB streams.
2. Use external player.
3. Switch to other PVR software.

Is there any way to use external player (like VLC) to watch TV in MP and still benefit from the EPG/OSD and recordings of MP?

Could be a config setting.
What is not so good about it?

Do you use xp/vista/7?

 

[roeeb]

I am using Vista. The only think I can control is the deinterlacing method. It also automatically reverts it in Cyberlink decoder tab in MP configuration to "Auto detect" even though I set it to "Force bob".

The picture in general looks blurry (after deinterlacing) especially when fast movements occur.

Did you used "unlocked" SAF?

 

[roeeb]

No, I only tried the one you posted on the forum. What features the "unlocked" SAF has?
