Re: Multiple DirectShow Window problems


(Hopefully) Final update: I (finally) took once piece of advice that Thore
Karlsen offered: I had switched from the VMR9 to the VMR7 renderer at his
suggestion, and the problems changed, but didn't go away. I finally tried
the VideoRenderer, (as opposed to VideoMixerRenderer) and that fixed all the
problems.

It is interesting to note that there were still some problems with both the
nVidia 6600 (card from PNY) and the 6800 (card from Leadtek if it matters)
in rendering certain MPEG files. One file had a line of random noise along
the top of the player window, that interestingly didn't stop even after the
playback stopped at the end of the file. When the end of the file was
reached, the State stayed in VFW_S_STATE_INTERMEDIATE longer than any other
file I'd seen, and it timed out in my program giving me an error message.
This could also be an interaction issue between the cards and the codec mind
you. These problems went away when I re-installed the ATI Radion X850XT
card.

My only issue now is that the VMR's, when they worked, started more cleanly.
As it is, although I paused the playback window on the first frame of each
of my MPEGS, when I first reveal them (by hiding the window that is covering
them) the first frame seems to not render cleanly. It's hard to say what
I'm seeing, because it is so fast, but there is some issue there that I
don't think was there with the VMR7 or VMR9.

Thanks to Mr. Karlsen and TMH for all their help!
