Please look my capturing performance...

[Anderson]

Look my config, K6 500 scsi 2gb (windows 98 within this), 40 gb ide, isa soundblaster 32, 128 mb ram, pinnacle studio pc standart drivers for it. With this config, using audio 22k/8/m mjpeg quality 20 25 fps, I have perform of: 201233 frames, time 2:14:18 and 204 frames dropped. This quantum of drop frames is ok or is possible improve it? Using Win2k, WDM drivers and other software unlike virtualdub can I get better results?

I use a K6 500 with a matrox card and capture with matrox mjpg and picvideo mjpg 44k sound, quality 20 averaging 2 drops per hour using AVI_IO

Please, let me know more details: about your motherboard, grafic board (agp?), Is your hd 7200 or 5400 rpm ? Do you have a single hd or you capture in another hd? Do you use Win2k or 98? Do you capture in 640x480 or minus (I use 320x240)? Do you use the WDM drivers? Did you have done some tweak in your configuration? Maybe in the my capture card the problem? I'm looking for where is my bottleneck, I believe that you and others users can help me. Thanks.
