[mythtv-users] Firewire and DCT-6200

[Alex Brekken]

Wow!! Big improvement for me. As I posted earlier, my firewire reliability
was only around 60% (at best). Since running these commands I'm batting 100%
so far. It's only been a day, but I've tested it quite a bit and haven't had
any "false starts" from either live tv or recordings from firewire. I also
changed from point-to-point to broadcast, and changed the speed from 400
mbps to 100 mbps as suggested. I doubt these were the reason for the change
since I've played with those settings quite a bit before with no improvement
in reliability.

Question: since I have no idea what these plugctl commands really do, I'm
wondering if they need to be re-run anytime the machine is rebooted...?

Thanks Curtis for the great find! I know there's quite a few other Firewire
users who have the same reliability problems, so I hope they give this a
try.
