Fireface 800 Woes

Hey here's an issue for you guys to shed some light on and save me from the depths of despair! :D

I've finally got my RME Fireface 800 "running" with Sonar 5.2 PE and
Gigastudio 3, using a standard 1394a (regular FW) PCI card...

All buffers are set to 256, ASIO drivers (seem to play nicer than WDM for
me) and I have a Audiophile 2496 card installed taking SPIDF sync from the
Fireface.

THE PROBLEM: Audio playback is "clean" (no pops, clicks or distortion) but
plays back choppy, with MIDI stopping and stuttering along the way and
playing out of time. You can actually see the position bar slowing down,
speeding up and stopping on the timeline.

So my question is, could this be an issue with my firewire card/cable or
perhaps a sync setting I have off? There is absolutely NO problem when I
use the Audiophile 2496 to do the same tasks, so it's not a processor
issue - I've experimented with various buffers/settings to no avail, any
help/thoughts would be awesome!

Thanks!
