ffdshow: poor quality when watching 2 vids @ same time

[cochese]

Hello everyone. It has been a long time since I've visited, but I know it's the place to go for expertise. I'm far from a power user, neverer tweaking ffdshow because I really only use it as a codec pack (one install, plays everything!).

Recently I noticed that if I'm playing a video, and then open a second one, that the picture of the second playing video becomes washed out...it has like a pink haze to it, with a light verticle line going down the left side of the screen. This only happens when playing more than 1 video at a time.

I thought maybe it was the latest build I installed, so I went back several old versions & it still happened. The build i have installed now is 11.29.05 and I am playing it with MPC. If anyone has heard of this issue (I've done tons of searches around the web, with no luck) could you please help me out?

Thank you very much for your time....

P.S. it doesn't matter which player I use to play the second video, the picture is still messed up - so I don't believe it's a player issue.

I had a similar problem, and the reason was I used Overlay Mixer as renderer (output setting in mpc) and thus ffdshow didnt get activated for the 2nd movie. A limitation in the overlay mixer. I changed to VMR9 Windowed and got identical and good playback on both movies. So...I hope that will help you too.

btw, people usually don't help out much on this forum from what I can tell and by experience... :P

My picture dont apear totaly washed out. It becomes (much) more blocky, with more ringing and the playback is not smooth. Even if the other player is in an idle state. I don't know what output I use, and can't verify it now. But VMR9 isn't slower for who don't have an external video card? I'm not even close to have an high end system, so I need speed.

There is no way to make an workaround about it? And when I encode with virtualdub decoding with the FFDShow VFW, and want to see a movie at same time? I can't?

I'll try your tip as soon as I get home. And if what you say is correct, then I doubly thank you for your help :)
