For DV, you need to keep about 3MB/s disk I/O all the time.
You may need a dedicated HD drive for a DV file.

Though it's best to have some feedback mechanism to adjust
timestamps, I have no plan to do so now.

Latest TI's 1394b chip seems to have some extension for hardware
timestamping for DV packets. I don't know details.
