        Darn - I forgot that 'quality' is not a 0 thru 1.0 number but is
        scaled by 100.

        Too many different ranges/scales :)

        (640 * 480 * 29.97 * 100) / (200 * 1024) gives 4495 or about 4495 * 8
        kbits/sec (~35900kbits/sec).   About half again as much as DV.

        With audio at ~1500kbits/sec (187 kbytes/sec) a total rate would be
        around 4680 or so.    That's 

        4680 kbytes/sec is a long ways from 10 or 11Megabytes/sec.  I was 
        curious if 'raid-0' was strictly necessary for capturing.  With 
        rates in the ~4-5 megabyte/sec range it would seem that thruput isn't
        the primary reason for a raid-0 setup.   Quite useful for catenating
        drives together into a bigger filesystem though ;)

        Cheers,
        Steven Schultz
