[FFmpeg-user] compressed data with sdti

> I'm working with many betacam sx tapes (http://en.wikipedia.org/wiki/Betacam#Betacam_SX) and trying to determine if there is a process to copy video data as-is from the tape to a file without requiring transcoding or uncompressing the data (similar to dv tape over firewire). I can output the data over SDTI which is a protocol to send compressed video data in the usually visual area of an SDI stream. I tried capturing an SDTI output of a video deck to an SDI capture card to an uncompressed file. I see that the encoded data is stored in a single field of this resulting v210 codec so I hoped to take only that single field and parse out the compressed data (mpeg2 from the tape); however in the resulting data I see none of the usual identities of mpeg2 (gop headers, 0x0001b5, etc).

Full command line and console output please?
-r
