I've heard that while watch football and other video with fast moving scenes, the pvr-250 will drag a little and create artifacts. is a software encoder better? or is there another option? I've heard that the pvr-250 is the best way to go, but I find it hard to believe. Thanks for any help you can give...

Cody - try *increasing* your capture resolution to 720 x 480 and bitrate to 5600. Don't ask me why, but the ivtv driver does not play nice with the default 480 x 480 and lower bitrate. Fixed my problems anyway.

Well now that's a fine solution if you have a terabyte raid aray or something to store those giant files on. What does that put your file size at about 4Gb/hr?

I record at 480x480 @ 2200 w/ both a PVR-350 and a PVR-250. None of these artifacts other people complain about.

4gb/hr is just too much space to ask.

My suggestion: Check what version of ivtv you're running. I'd update to at least 0.1.9vanilla, or even better, some of the new IVTV drivers that are coming out. They work well, but of course, are in development - so some unstableness is to be expected here and there.

Mine come in at about 3Gb/hr.

Coax,

I believe I am on 0.1.9...at least that is what it says in /usr/local/lib/ivtv/README. I wish I could find the thread that described my problem and proposed this solution, but the searchable archives appear to be down on the ivtv site. I am pretty sure I saw this message first:

http://www.poptix.net/ivtv/current/msg00182.html

...and then I searched for the thread he described:

Re: [ivtv-devel] Video Glitch in 1.8 (was: Tinny Audio, old drivers,and ic2 2.8.0)

where somebody suggested the resolution / bitrate. It has been an acceptable solution, but I'd love to be able to do a 480x480 @ 2200 and get the same quality I get now. I'll have to check those development drivers out.
