I do have the im_avisynth plugin or whatever its called and the cm_avisynth plugin or whatever that one's called. The avs file opens in both windows media player and virtualdub without the problems I'm having in premiere. And I added the # to the last three lines.

Add-On to earlier whining about blank screen:
So I have that black screen. I set the clip in "interpret footage" to square pixels, "deinterlace" is checked in the clip's "frame hold" options, and "always deinterlace" is checked in the clip's "field options." I then open the clip in the source moniter and set the zoom to 100% and get an image--the slanted streached lines of interlaced video I assume.
----------------------------------------------------------
Okay so that add-on's probably a tad redundent, but basically I still can't see the deinterlaced...well here:

Is this even an interlaced image? Am I even asking the right questions? Thanks.
