6.04 Front end only stutter on some video playback

My Front end only machine suffered a hard drive crash so I did a fresh install with 6.04 ( I was running 6.03 or maybe 6.02 - don't remember). I also updated my backend machine (which is a backend / frontend combo machine) to 6.04 with pacman.

I'm getting stutter (video and audio) when playing back certain video files (DVD rips transcoded stored in storage groups on backend machine) . This is new behavior since the switch to 6.04.

Here's some frontend log entries from play back of a video file:

Can't seem to figure out what changed to make the frontend stutter so much!
