Hi, I have an issue with mpeg 2 video playback on MP. I'm by no means an expert but when I watch mpegs and dvds with either WMP or PowerDVD the video looks like it does watching it on TV. When I watch it on MP almost like watching it without the hardware acceleration or having the overlay settings turned on on WMP because if I turn these off on WMP or PDVD it looks like it does on MP. I can get a good clean image with FFDSHOW but just doesnt look 'broadcast' like it does on WMP or Powerdvd?
Have checked all hardware accelerations and they are all turned on. Help please!!

can you check your directShow graph in both cases to check did you use same decoders or not?

thanks for the reply. How do I check this? My MP config is Cyberlink Video/ SP decoder 7 and when I look at the properties on the same file in WMP or PowerDVD it says the same. Is this good enough? Been playing, on WMP9, turning on/off 'use overlays' on the avanced video performance options toggles the look of the video I was trying to explain before, if that helps?

Which renderer do you use?
The best way is to run GraphEdit in both cases, connect to graphs and post here screenshots.

How do I use this prog? downloaded it but cant see how to make graphs? where do i find what renderer I'm using? sorry for being a complete newbie!

One way:
1. Play preferred material in MP window mode
2. Open GraphEdit -> File: Connect to Remote Graph (or CTRL+G)

or

MEDIAPORTAL - free MediaCenter HTPC Software - TestTool exports direct show graphs

I've sorted this problem by reinstalling MP and using the 'bob' interlace to give the video braodcast look. However all my 4:3 MPEG2s (only MPEGS, other formats fine) are stretched with 'normal' as the aspect ratio when in widescreen. On my PC monitor (4:3) the files are now in widescreen and I have to select stretch to get it 4:3! I've only reistalled MP! My external programs still play the files as 4:3 in all conditions! I'm lost! Im using the MPV MPEG2 decoder but all the decoders have the problem with the size format! Please help
