In .21 I seem to remember a setting for Mythvideo that has it scan the
filesystem for new files every time you open it. Try disabling that perhaps?
It's got to get the list of files somehow, so it's database or filesystem
access. 600K/s seems quite slow for either unless your backend or fileserver
just can't keep up. I have a somewhat large directory of video files on my
server that the FEs access over the LAN and it only takes me a few seconds
to scan the whole thing from either FE. My FEs mount the video filesystem
with NFS and autofs.

I'd check the transfer speed from your fileserver and make sure it's not
getting bogged down. Heavy CPU load or lots of other I/O will slow down
access for your FEs. Also check the network, make sure you're connecting
both machines at the best speed your network can handle and they aren't
falling back to 10M for some reason. Check the database logs as well,
perhaps it's having issues.
