these were h264 encoded files that had previously worked, but one day disappeared from the extender. what was weird was they showed up in media center, just not on the extender. and the entry for perceived type was still showing in the registry. i dont remember what I did in the end but I got it working again.
anyways when i posted this it was late and i was in bed, i just threw a post up in case some update had done something wacky and i was curious if others were having a similar problem.
