Yes, you can use RS422 for machine control and FW for the A/V. Whether it's frame accurate depends upon the deck. You might have to calibrate it. Otherwise, it might be a frame or 3 off. I have a DSR1800 and it's frame accurate. regards, sb On 9/29/05 5:13 AM, "Tim Selander" <selander at tkf.att.ne.jp> wrote: > Wonder if anyone here has used the low-end DV decks that also have RS422 > (Panny AG-DV2500, the JVC counterparts, or even the Sony 1500A).
