I am building a new box for use at my school as an event recorder and

video server. I used two HVR-1600 cards.  The system is Knoppmyth R5.5.  
The installation went fine and I downloaded the latest ivtv driver and 
cx18 firmware.

I had to boost the vmalloc to 256mb for both cards (4gb total in system.)

I am only using the S-video input so far.  I can view and record on both 
cards.

Problem is that when recording or watching live TV through the s-video 
port, every 67 frames, it jumps ahead the equivalent of one to two 
frames. It isn't dropped frames, it is a jump forward - it is like the 
67 frames are recording a smidge too slow, and at the 67th frame it 
jumps 2/30ths of a second to catch up (not sure that's what is 
happening, but that describes it.)  It is noticeable watching live TV, 
and it is on the recordings.  It jumps every 67 frames like clockwork (I 
ran through recordings frame by frame.)

It affects both cards on S-video. Don't know if it applies to over the 
air because I have no over the air inputs yet - will work on it 
tomorrow. Can't tell if it is the card, or the software.

If I run "cat /dev/video0 | mplayer -" it sends the output directly to 
the screen with no other processing, but it is so choppy I can't tell if 
the problem is present without Myth or not.

I tried searching the archives and didn't find anything (however, there 
are about 250 threads titled "HVR-1600 problem" that I just couldn't go 
through to figure out whether the problem was relevant.)
