Record Delay
What factors control the delay between the live signal and the video output ? Is it only a factor of how quick your disk can write ? and/or time required by the CPU for encode/decode ? Are there any settings that can control it in any way?
For instance I was wondering what kind of effect setting XP to give more prefrence to background process or setting particular processes to real-time would have. Interested if anyone has experimented much with this. mike/

Mike,
This delay is 99% in the Hauppauge PVR 250 / 350 Card. The reason is that the realtime MPEG2 encoder works on several seconds of video in a Buffer before it is actually even sent to the CPU on your computer. Even the fastest Disk and CPU in the world will not change this delay. A slow disk or CPU would result in jumpy playback or audio dropouts. But if your playback is smooth and you have no drop outs then you are probably going to be as close to live signal as is possible with the MPEG encoder card John.
