Well, I can't capture at greater than 320x240 anyway, so it works quite sufficiently for me (for TV shows anyway). Viewing fullscreen is of course quite ugly up close, but passable at a distance. I think I'll aim for about 400MB for an hour for stuff I want to keep. -- Cameron Kerr Email: [EMAIL PROTECTED] Website: http://nzgeeks.org/cameron/ --- This SF.NET email is sponsored by: SourceForge Enterprise Edition + IBM + LinuxWorld = Something 2 See! http://www.vasoftware.com ___ Mjpeg-users mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/mjpeg-users

After mpeg2enc (I'm following the steps in the HOWTO), I preview it with mplayer, and it shows up as a strange aspect, taller than it ought to be, and and with thick black side borders. Also, the image isn't terribly great on the bottom (colour out of whack, a bit, ahhh, streaky???). Hard to comment on that unless you give more details on the input source, command line used etc.. Is this normal for a SVCD (captured using PAL, if it matters). No I've yet to burn it (I'll need to go to a friends place to test it on his DVD player (plays SVCD also)). I wouldn't burn it if mplayer cant play it correctly.. Also, is it normal for a 30 minute recoding to take about 12 hours for mpeg2enc to process? Depends on the hardware and whether you are denoising or not.. On an Athlon 1800 with 512MB RAM I get about 11fps for mpeg2enc: ie about 85 minutes encoding time for a 30minute movie. Add to that the time to decode, scale and possibly denoise the input avi, it may take anywhere from 2 to 4 hours.
