Problem with Windows Movie Maker & adding effects.

Hi,
I've been trying out my new Sony TRV 950, by capturing video to my PC. The capturing works OK, and I can edit the footage and record it back to the camcorder OK.
The problem occurs when I try to add effects between the clips. When I'm recording the video back to the camcorder and try and add an effect, the LCD on the camcorder goes blue and freezes for a second (no effect is displayed) then the next clip is displayed and recorded correctly. Some of the effects work and are recorded correctly, but most do not.
Ive using the DV.Avi file format to send the footage back to the camcorder.

I only have a single HD, could this be the problem?


Any ideas?

Thanks.
My system,
Abit TH7-II motherboard, P4 2.2, 1GB RAM, 60GB HD, Win XP PRO, Audigy Sound card with Firewire, the latest version of movie maker

Hi

Update.

Ive noticed that also the video is now cutting out in places too.
very strange....

When I get the blue screen, the 16 bit sound icon goes out also, and when the video retuns it comes back.
The problem only happens between clips.

any ideas?

I dont have any software running in the background.

thanks....

Just to let you know ive fixed the problem with a new firewire card.

So it was a problem with my Audigy firewire after all.

I will be removing my Audigy soon, and going back to onboard AC97 sound.

Everything is working as it should now.

Thank You
