    hello folks! i don't know if this is already there in this forum! but i wasn't able to find anything similar to my problem. i got a notebook pc. its configuration is in my signature, the 2nd configuration.. i have AutoGK 2.26 installed on it.. and i was thinking if i could encode dvd to avi. so i installed this. i ripped madagascar onto my hdd.. but when i do the encoding in the autogk, sound never gets encoded :'( .. i dunno y!! i select the ac3 audio track.. and i've tried both auto and vbr (160kbps) as the output audio type.. but still i don't get any audio in the avi video. am i missing out anything here??? during the encoding it comes decoding audio, normalizing audio and encoding audio.. all do successfully, but then during the passes..(compressibility test and 1st n 2nd pass), the audio data is shown as 0 bytes.... y?? help me someone! i'm really confused.. thanks a lot!!

    ciAO!

    Read http://www.afterdawn.com/guides/archive/dvd2divx_anamorphic.cfm .
    You need to crate a D2V DVD2AVI project (few minutes) from the original VOB set. Sumultaneosly, you can extract the sound, but if you want to keep the original AC3 compression (you'll need more bytes, because an AC3 sound is 384 kbps, a MP3 sound has an appropriate quality at 128 kbps). More, be careful because the AC3 streams often have a delay which must be corrected when you extract it (ReJig in IFO mode is OK, there's a box to check, for it. I don't know if DVD2AVI takes it into account, when it demuxes the AC3 stream. It does when it extracts the sound by decompressing it to WAV).
    Apart the sound problems (you can re-encode the un-compressed WAV to MP3 CBR later), the D2V is the 'pointer' which allows VirtualDub to load the VOB, oce you have one of these two programs installed:
    - VFAPI Reader Codec (read http://www.afterdawn.com/guides/archive/dvd2divx_anamorphic.cfm )
    - AviSynth and its plugin named MPEG2Dec3dg.

    You need either to learn a little of AviSynth (look in http://www.avisynth.org and its tutorials) or study the tutorial I pointed out.

    Avoid using AutoGK, for this. VirtualDub is THE (free) tool to use.

    Good work....

    absar..Don't know if this will help..but a friend of mine had a similar problem with the West Wing..the audio was so low U could not hear it..What he did was use Womble Mpeg to VCR,TO JOIN ALL THE VOB's thus converting them to an Mpeg format,then AutoGK..It did work..& it doesn't take as long as it sounds..just remember to import your video backwards for simplicity..IT WAS ABOUT 10mins all together..Just try a sampling at first..convert the 1st vob to mpeg then AutoGK FOR A SHORT SAMPLE
