Synopsis: Problems with Various MPEG-2 Codecs

I have decided to come back to Media Portal and buy the TV Tuner again after returning it following as a self punishment of me not getting on with my high priority commitments. I talked about it at this forum http://nolanparty.com/mediaportal.sourceforge.net/phpBB2/viewtopic.php?t=8072

Anyway, I cannot find a decent MPEG-2 Codec to use for Digital TV. Here are the problems I have encountered in all the codecs I have tried.

MPEGDEC: Nearly the best to use. However, it does not automatically detect the aspect ratio of the DVB broadcast and it can be annoying having to manually switch from letterbox to full screen mode and vice versa to suit the channel I am currently viewing. It would be convienient to use normal mode and automatically select the aspect ratio like with DScaler and Cyberlink.

DScaler: Nearly the best to use too. However, Bob deinterlacing does NOT work in VMR9 mode. I am forced to use VMR9 because when I use overlay, the peformance is unacceptable, the sound and video is choppy and even moving the mouse makes it much worse!

Nero: Overall very unreliable, horrible deinterlace engine by blending fields together, not displaying one by one. I absolutely hate this method of deinterlacing as it makes a 50Hz PAL broadcast into a 25Hz. Also, this gives black and white results at times too!

CyberLink: Does not work properly in VMR9. Also has a horrible deinterlace engine when used in programs other than PowerDVD just like Nero. Overlay mode is very unreliable and choppy and DXVA doesn't speed up the system, it makes it much worse that the mouse pointer struggles to move!

Although I am using RC1, the bugs are the same as the earlier release 0.1.3.0. In 0.1.3.0, recording does not work so that's why I use RC1. Most other bugs will be posted in the dedicated RC1 forum.

p.s.
you can download trial version of nvidia pure video decoder
well it said on the requirements page that parhelia are compaitable with the required dx9 features. vmr9 works nicely for me, it's just these dodgy codecs.
