LinuxQuestions.org - dvgrab ignores -format option?

So I'm using dvgrab to pull video from my DV camera (Sony HVR-H1P). I'm writing a script to pull the video into temp files, then use ffmpeg to split the audio and video into separate files. To minimize quality loss, I want the initial transfer to be done to RAW format...

BUT, dvgrab seems to be ignoring my wishes:

Code:

fukawi2@morpheus /tmp/testing  $ dvgrab -format raw -autosplit -timestamp -size 1998 -csize 4400 -cmincutsize 10 testing-.dv

rom1394_0 warning: read failed: 0x0000fffff0000414

error reading config rom directory for node 0

Found AV/C device with GUID 0x0800460104a25be0

Waiting for HDV...

testing-2010.07.06_15-43-18.m2t: data

Note that it is writing to an "m2t" file, even though I specified `-format raw` *and* added the .dv extension to the base filename :(

vlc plays the file and the `media information` dialog reports the video stream as being `MPEG 1/2 (mpgv)`
