We just got two MacPro workstations with Kona LHe cards this year. Specs are dual 2.66, 4gig ram, using pairs of striped Medea SCSI Ultra 160 RTR arrays.
Whenever I tried to do a batch capture of more than say.. 4 clips, it would inevitably conk out with Final Cut's 'Tape Trouble.. Check VTR...' message. This is using a Sony DSR-1800 DVCAM deck controlled via the Kona's RS-422 port.
So last night I tried plugging a 6-pin Firewire cable between the MacPro and the deck, switching the deck's remote control from 9-pin to iLink and then changing only the Deck Control setting in the Capture Preset to Firewire NTSC.
From that point, it batch-captured fine. I could consider this a means-to-an-ends I suppose and just keep it running like that. But wouldn't this go to say that the problem is likely specifically with Kona's serial controller?
