[mythtv-users] Firewire and DCT-6200

[Curtis Stanford]

Congrats! My box is on Node 1 but I don't think that matters much.

You don't need to set the speed with plugctl. I just set it to 100 in  
the mythtv-setup GUI and the backend sets it for me. I don't think it  
matters that much what it's set to but 100 is plenty fast enough (not  
sure about HD??)

I'm still having problems with some recordings being cut a bit short,  
even though there are no errors on the backend. Otherwise, working  
great! Next stop is to try some HD!

Have fun.
