KVCD is a modification to the standard MPEG-1 and MPEG-2 GOP structure and Quantization Matrix. It allows you to put more than 120 minutes of video on a single 80 minute CD-R/CD-RW. The KVCDx3 template creates 528x480 (NTSC) and 528x576 (PAL) MPEG-1 variable bit rate video, from 64Kbps to 3,000Kbps. One of the other templates uses 352x240 (NTSC) or 352x288 (PAL), allowing up to ~360 minutes on a single 80 minute CD-R. You must burn the KVCD MPEG files as non-standard VCD or non-standard SVCD (depends on your player) with Nero or VCDEasy. The KDVD version of KVCD allows up to 6 hours Full D-1 720x480 on one DVD, or about 10 hours at Half D-1 352x480. Because KVCD and KDVD are not recognized "formats", the MPEG files created may or may not playback in your standalone DVD player. More info at kvcd.org
