    Hi, I have been following this guide:

    http://www.afterdawn.com/guides/archive/convert_avi_to_dvd.cfm

    to convert a DivX Movie to DVD format. I followed it all the way to the last page:

    http://www.afterdawn.com/guides/archive/convert_avi_to_dvd_page_4.cfm

    But I want to decrease the "average video bitrate" in tmpgenc so the file is only 800mb in size, It won't let me though! 2000 is the lowest I can go. I am currently trying to put an episode of lost onto DVD.

    Why can't I decrease it below 2000? (file size 2mb+)
    I have the full version of tmpgenc plus 2.5.
    My video is DivX and fps is 23.97 so I chose NTSC as advised.

    Sorry , but probably TMPGenc found that you must have sort of 'minumum bitrate' not smaller than 2000 kbps, to correctly encode 720x480/576 movies into DVD M2V videos.
    For instance, if you had a SVCD movie you could have reached less bitrate, e.g. 1500 kbps.

    If you want to be able to decrease the bitrate of your movie, you can try to decrease its resolution (convert 7200x480/576 to a 480x480/576 movie and you'll be able to lower its bitrate).
    After all, you cannot have all (small size AND high quality), isn't it?
    The simplest way I know: load that AVI with VirtualDub. Do Video__Filter__Add and add the Resize filter.
    Fix 480x80/576 the desired resolution and choose, as 'filter mode', Lanczos3 (the best one).
    After that, simply start the framaserver (if you've already istalled, otherwise install it before doing so, by clicking to the auxsetup.exe file which is in VirtualDub's directory) and make what you wanted to do with the old 'movie.avi' to the framaserving file (e.g. 'movie.vdr').

    Sorry, but which reasons could you have, to want to fit a DVD movie in a 80' CD-R?
