I'm using Adobe Premiere to edit spots for a TV station. The preview of the imported digital video looks fine, the outputted video looks fune in WMP after muxing the audio and video together, but when I try to play back on the broadcast system (which records the original files I'm editing and plays them back fine), they're stuttery and jumpy whenever there's any medium to high motion. Any help appreciated, as I have to edit about 100 spots in 72 hours, and the old production method is out of commission (off tape).
