Video recording "glitching"

[dr g]

I notice when I record video (I believe it happens in all resolutions), after some time I will get "hitches" in the final video. These are on the file and not a playback issue. I suspect it has to do with the transfer to SD, as they only happen after a little while, then the buffer probably fills up. Does anyone NOT experience this? If so, what kind of SD are you using? I'm hoping changing SD cards might help.

This is the stock SD card. It is a Samsung card labeled Class 2. I have reformatted this SD card once already and have about 5-6 gigs on it.

I've also experience jittery video recording, with really bad jumps in it.

I didn't have that problem on the original 8gb SanDisk card that came in the phone but I switched to a 16gb SanDisk class 2 card and it happens with that one. Probably need a faster card.
