[mythtv-users] HD Woes (so close to working, dual-channel RAM question)

After trowing an even 'bigger' processor at it, I am now able to mostly play
back 1080i, but it still pauses every few seconds. The new processor is an X2
3800. I bit the bullet on the dual core to hopefully solve this once and for
all, and be able to comm flag/transcode while watching shows.
I've been playing with all the settings, but so far the best is using libmpeg2.
I don't see a difference between any of the interlace methods. All take up 100%
of one CPU.
I'm currently running a 720p mode from the mode pool. Even watching 720p videos
was taking up all the CPU of the Athlon 64 3400 before the new processor (did
an exchange with newegg). Because of the 720p problem, I stop worrying about
trying to get a 1080i modeline to work for now.
So my current question is how much of a difference does dual channel memory
make on a Mythtv system? I am an idiot and did not realize I actually had a
1gb and a 512mb stick and not 2x512. In the bios on startup, it says it's
running in single channel mode.
Thanks,
Nate
