Well, the patch you have to work with essentially does a poll every 1/4
of a millisecond (a rate of 67 times per NTSC field while polling) with
a wait between the polls. If you're still getting artifacts, then I
suspect your artifacts problems may not lie where I'm looking right now.
I have no artifacts with analog captures, so let me get through this
first problem and then I'll ask more about your symptoms. I don't have
a 3 HVR-1600 card setup. You may try setting enc_mpg_bufsize to a value
different than 32 kB. Setting it higher will make you less likely to
lose buffers due to the firmware timing out when it sends buffers to the
driver. Setting it lower will make the loss of any one buffer of less
impact to the stream, and setting the analog capture to provide TS vs
the deault of a PS may help too.

OK.
