DCS 1394 problem

I have set Delius as Master for clock. I have also try to connect Verdi with Delius alone thru 1394. It plays SACD for about 1 hour. All of a sudden without any reason, Delius starts to play intermittenly. Couple of hours later, Delius shows "search.." and could not regconize Verdi all together. Have you experienced this situation? Philip

My situation is not the same. I could see the Verdi is playing fine thru its display. Tracking is not jump. It seems that the data is not picking up by the Delius. Delius displays "search.." at all time.

Please let me know who service DCS in the US. Any information?

anyone with an used working 1394 card available?

finally 1394 cards are replaced with new ones and units are working fine. I am looking for the small card that is attached to the rear chasis. If avialble, please email.
Thanks.
