Hi Peeps!

I'm hoping someone can make my day a little brighter and help me with this strange fault.

First of all I own an 'AMD Athlon 2700mhz', '512 MB Ram', running 'Windows XP' - With latest S/P.

The motherboard is a 'ASUS A7N8X' with onboard Sound. (NVidia with the lastest s/p)

I capture video from my analouge video camera through my Pinnacle Capture Card, using the software 'Intervideo WIN DVD Recorder'. I record directly into MPEG 2 DVD Quality, so it's the best I can get. (I don't bother editing, just capture and burn baby)

I go from my analouge video camera, directly in to my "line in" on my motherboard, with the level near the bottom, so it doesn't clip on loud noises!

My problem is: The video looks great, the sound is fine. However, if I have a constant sound, like a ferrari revving on the spot... it will sound like ... vrooooo *quiet vroom * vroooo *quietvroomm* vrooo
instead of vrroooooooooooooooooooooooooom

LOL.

Basically ,it's dropping the sound volume every other second on loud constant noise, so you get noise then nothing..... only noticeable when something constant is making a noise. Speech and everything else is fine, its just constant loud noise, you hear the dip in volume...

Its a pain in the backside! I never had this problem befoire, but I use to run Windows 2000 before... do you think it could be XP?

If this makes sense, can anyone give me a few pointers at all?

Thanks
