That is a hardware compression device right?
Sorry I can't be more help, but I did want to let you know that
quality IS possible.
I wish I could glean more from your experiences but I am using a bt8x8
solution so I can't even try to apply your "lavrec" usage to a
solution for my hardware. It appears that lavrec only deals with
zoran video-capture devices, like the Miro/Pinnacle DC10(+), the
Iomega Buz or Linux Media Labs' LML33.
Thanx anyway.

The sort of jerkiness you are talking about is typically the result of 1
of 2 things:
1) Hard disk speed is too slow. To fix this, use hdparm to optimise your
drive settings, or use a compression algorithm with higher compression
ratios.
2) Your CPU is too slow to compress the video real-time. In this case,
use a faster compression algorithm.
(Possible 3: If you only get this when recording from a VCR, try the
VCR hack that was posted to the list a while ago - this helps a lot if
your VCRs playback timing is slightly off.)
You may notice that these two are contradictory - so you need a fast HDD
or a fast CPU, or preferably, both.
I have an Athlon 600, and use DIVX4rec with the "-dq3" option. It never
drops any frames, and the quality is still pretty good. On a PIII-800,
I use "-dq 5", and the quality is awesome...) On my old K6-2 300 I had
to use QTrec, and later convert to divx, but two lossy compression
stages are a bit bad for quality. mp1e is the best low-cpu option I
have ever seen, but I have had many problems with A/V synch.
