Hello,
I just installed Arch on my Raspberry PI.
I Created 512mb swap file and overclocked the CPU to "Turbo Mode" per the instructions in the forum.
After overclocking to Turbomode, I can now finally see video but it is very choppy when playing off my LAN. RaspBMC plays perfectly fine.
Here is some data at time of play
