Dropping Frames and it didn't used to.

[kustomkla80]

I've had my capturing with virtualdub down to a science for a while, capturing a whole show and dropping zero or maybe one frame. Now all of the sudden it's dropping 10 in 3 minutes, and I haven't changed a thing.
What's happening to my setup?

Some possibilities.

Are you capping to the same HD?

Maybe it's time for a defrag.

You could have changed a setting without remembering such as selecting RGB24 instead of yuy2 (which is usually faster) or an option in your video or audio compression codec etc...

Are the 10 frames all at once or spaced out over the cap? All at once would indicate an interrupt or a brief bottleneck somewhere. This can occur if you are running something else at the same time (even your virus checker or your firewall) can sometimes wake up at the wrong time and draw on the cpu or hd.

I defragged and it's working fine again. Thanks. I captured 40+ minutes with 7 frames dropped.
