I haven't played with the new version however from the info at your web site, fxtv is looking outstanding!! Good Job! Amancio >From The Desk Of Randall Hopper : > URL: http://multiverse.com/~rhh/fxtv > > Got some new toys put into this version. > > - Image Save-to-Disk - saves the last frozen image (TIFF) > - Audio Save-to-disk (Raw, AU, AIFF, WAV, VOC, MPEG-2, MPEG-3) > - Video Save-to-disk (TIFF sequences and/or MPEG video stream) > - FPS control added > - Doesn't kill the CPU anymore.
