I've read a lot about audio stuttering on here...hopefully you guys can help on this one...
First, the setup: the MOTU 2408mk3 is the master clock...Tascam DM4800 digital console slaves to it via word clock, audio into console via MOTU's firewire from the MOTU PCI card, running Nuendo 3.2.1154. Checked all settings in console, MOTU, and DAW and see nothing obvious wrong.
When a video file is in the DAW window, audio stutters bad coming out of the MOTU. Delete the video file and audio returns to normal. Undo delete and put video back in window and back to stuttering. Ran a latency test and shows bad pipeline. Went thru Windows XP device mgr and individually disabled everything possible looking for a bad driver..no luck...messed with every setting of buffers/latency, etc. on Nuendo and MOTU..no luck...digital console seems set up correctly with correct sample rates, etc...same frame rates in DAW...does it on every video project...running XP with Dual Core processor and 6 gigs of RAM! Disabled several background programs possible in XP and even tried some of the XP performance tweaks found on the web. CPU never really gets above 55% on performance meter.
Even had troubles with stuttering when trying to preview CD cuts with Nuendos Import from Audio CD function..dont knowe if that helps.
Running 24 chanels into DM4800 via TDIF. In the PCI Audio console, if I disable every onne of the inputs and outputs except for Bank A, Channels 1-2. The stuttering and gurgling goes away. As I slowly add in the Bank A, then Bank B and Bank C i/o the stuttering comes back worse and worse.
Can't find anything specifically like this on the forum...Running out of ideas...
Thanks!

Hey Babbott:
Costello here!
You're talking about Windows XP, so the issue is a tough guess in a DP/Mac only forum. You may want to copy the question in the Windows forum a couple of slots down on the index page.
However-- it sounds to me that you have a video thru-put issue if things work fine without the video and go wonky when the video is put back in.
I would consider either a different hard drive bus, one each for audio and video (firewire and SATA, or SATA and eSATA).
What I can't do is address XP settings, so check the Windows thread for MOTU hardware on PC. Another PC user will likely get back to you quickly. Gladly, your issue doesn't sound at all insurmountable.
Best of luck!
