This problem stems from using BSPlayer, ffdshow, and avisynth to double the frame rate on the fly using interpolation.

work just fine at double the frame rate for the first 5 seconds or so. Nice and smooth. Then CPU usage for BSPlayer just decides to sink down to 60%, 40%, 20%, then 0-5%.... and it won't come back up.
When I seek to the middle of the video the first few seconds play just fine, and then it drops gradually down to 0-5% CPU again...
It seems that seeking "resets" the CPU usage back up to normal levels.
BSPlayer just stops using the CPU for some reason. Same thing happens even if I set process priority to above normal/have nothing happening.
This thing even happens if I resize to something smaller like 800xwhatever. The CPU maxes out at 80%, and without even hitting 100%, it drops down to 0%. So in this case it's clearly not the CPU not being powerful enough considering that it never even hits 100%...
This is really frustrating. If the CPU can't handle it, it should be at 100% all the time but with choppy playback.
Any idea what's causing BSPlayer's CPU usage to drop to zero?
Using the latest version of the free player. Thanks!
