There are 2 possibilities here: 1) The video is actually recorded @ 60Hz (in other words, each field comes from a succesive frame). To solve this, you will need a deinterlacer, or just capture with a vertical size <=240. 2) *MOST LIKELY* The Bt848 is loosing synch - this can cause one field to belong to an older frame, and occurs frequently when capturing from a VCR. Install the patch that was posted here a day or two ago (lost the link...), or use bttv2 with "VCR Hack" enabled. -justin
