Whenever I record from clearqam using this card I frequently get small "glitches" in playback. Playing these same files with mplayer yields things like: demux_mpg: 24000/1001fps progressive NTSC content detected, switching fra= merate.

There are no messages whatsoever in the kernel log when this happens so whatever is happening the cx18 driver is being silent about it. I also can't very easily blame the cable signal as an HVR-950Q recording from clearqam at the exact same time never has these sorts of artifacts. Any thoughts why these only happen on the HVR-1600?
