Is playback of .eyetv files possible?

I’m still trying to find a way to play my Elgato .eyetv files from a network drive. I’ve installed Perian and Mplayer codecs and tried playing from NitoTV and XBMC. XBMC crashed out, NitoTV stuttered unusably in ‘mplayer’ mode and failed in ‘mixed’ mode.

Playback of Quicktime files is fine from the same network share.

Anyone know how to get playback of .eyetv files working?
