[mythtv-users] Glitches in firewire capture from DCT-6200

Thanks guys, yes I changed the speed setting in mythtvsetup to 400 mbps.
Now, plugreport shows that the data_rate=2 and stays there. However, it
didn't seem to fix my display issues.
It's not a stuttering necessairly, more of a slow-down - like it's in slow
motion for a second or 2. -it does this every 3 or 4 seconds. "normal
speed, slo-mo, normal speed, slo-mo," etc, etc. The video itself doesn't
break-up at all during this problem. It doesn't do it all the time, but
it can happen on any channel. I see it both during liveTV viewing as well
as on pre-recorded shows.
The firewire capture is happening on a slave backend box, which is an older
Dell pentium 3 1gHz machine. I suppose it's possible that the machine
itself is to blame (issue with PCI bus?) but I don't think the hard drive is
the problem. It's a newer 7200 RPM Western Digital drive with 8 mb cache.
Any guesses? I'd love to be able to utilize Firewire capture, since it's
much more reliable now thanks to those pluctl commands - but if I can't fix
this video slow-mo issue than I think I'll have to ditch it.
