Crackling occurs after 1 minute of video&audio

hi iam trying to use the MS VX1000 thru the windows movie maker but the movie maker does not detect the camera.
Pls advise a solution

Hi that all sounds to me to be a fairly classic "Electret" Mic problem.

I have seen .. lol.. or rather, heard it, a few times B4.. the "Frying" sound you hear is the faulty electronics in the Electret microphone..

I would try replacing the Mic, if you can get one the same size, it shouldn't be too hard to Open the camera up, unsolder the old Mic, & replace it. There are really only a few standard Electret Mic inserts...

As an aside, sometimes it can simply be a bad solder joints to the wires on the actual mic itself, ya may wanna try good reflow/resolder first B4 ya replace.. This sometimes is all it requires...
