    After converting an XviD video file to KVCD format using WinAvi video converter, I burn the converted file from Nero using Video CD as the disc type. The resulting disc plays fine in all of my standalone DVD players, but the time code (duration of the video) is listed incorrectly by the players. Also, The time code ticks away faster in some parts then in others. The partictlar video I just did showed a duration of 1 hour and 28 minutes, both in the original XviD computer file and in the converted (WinAvi) computer file. The standalone players report the video duration as 1 hour and 4 minutes. I am wondering if these outcomes are normal, or if I can do something to correct this next time. It's obviously happening in the Nero (video cd burn) part of the process.

    i started burning kvcds about a week and ahlf ago and this same problem perplexed me for a bit, but i came to the solution pretty quickly:

    the reason your timecode on your stand alone player is off is because its firmware doesnt officialy recognize kvcds. its made to recognize vcds and maybe svcds. the longest a "standard" vcd can be is around an hour. remeber, the kvcd notch matrix is a sort of "hack" made to make vcds longer than an hour. it stretches the video out by packing more into the same area as a normal vcd. when the stand alone player is reading the kvcd it thinks its reading a vcd and wont show its time code properly, because to it the disk couldnt be longer than an hour even though it is. the reason it speeds up and slows down is because you probably converted the video in variable bitrate. the timecode counter in your stand alone player probably goes by bits, not any sort of actual timecode read off the disk. if you divide the real lengh of the movie by what it says it is youll get the ratio, wich you can check to test this theory if you dont beleive me. kvcds are weird, but they rule!

    you havent done anything wrong, you did everything perfectly. your dvd player just doesnt know how to properly timecode a kvcd (im not sure any can actualy).
