    I had two .avi files that I needed to join with two separate sample rates.

    1) I extracted both audio tracks as .wav
    2) Converted both to .mp2
    3) Disabled the original audio tracks of the two .avi and did a direct stream copy of each with the new .mp2 tracks.
    4) Joined them in VirtualDub

    Here is where I have trouble:

    5) I try to open the movie in TMPGEnc Plus but it does not read the audio. I also tried opening the file in VirtualDub again (now one joined .avi with .mp2 audio) and it says no decompressor has been found.

    Any ideas?

    You're trying to convert mp2 audio in tmpgenc to mp2 audio. Why?
    Follow step 1 through 4.
    5) Extract joined audio in virtualdub as mp2, set aside.
    5a) If extracted audio is .wav, convert to mp2, set aside.
    6) Encode video only in tmpgenc.
    7) Author m2v from tmpgenc from step 6, with mp2 from step 5(or 5a).

    Not sure your understanding me:

    1) I start with two avi files with different sample rates. I extract both as .wav and converted both to .mp2 audio.

    2) Then I need to join the two .avi files together so I can encode one large file on TMPGEnc Plus (to later burn to DVD). I direct stream copy each .avi file with the new, re-sampled .mp2 audio tracks.

    3) I then join both files. Now, when I try to open the file in TMPGEnc Plus it does not read the audio.

    Ok, what I don't understand is this: a mp2 is a audio stream belonging to a mpeg-2 file...how do you mux one of these with a .avi?

    do you mean a .mp3 audio stream?

    sample rates different? so you are converting 2 different sample rate files to one common rate b4 joining?

    have you considered using BeSweet GUI to convert the different audio sample rates to a common one...before joining.

    You can't open a .mp2 audio file in a mpeg encoder to convert to same(as pointed out by rebootjim) (2) VirtualDub does not support(have a decompressor) for a .mp2 file.

    Go back and match the sample rates for the .avi video and the .wav/.mp3/pcm audio files mux with the .avi then import to Tmpgenc.

    AVI don't work with MP2 audio.
    I cannot understand the 'sample rate' stuff you speak about ('sampling rate problem' appears in VirtualDub only if the sounf was compresssed MP3 VBR instead MP3 CBR, but, you just to extract the sound as WAV.
    After you have the sound as uncomplreeed WAV, you can make an AVI with uncompressed sound (loading the AVI with VirtualDubMod and disabling the old stream + joining the new strea; read the FAQ) or you could convert the streams to AC3 192 kbps 48 kHz, then put them in the AVIs with VirtualDubMod, finally demux the joined sound to author the DVD with it.
    If you do so, you can ignore the fact that TMPGenc doesn't load the audiuo, since you need TMPGenc only to make the video stream.

    Here, let me just make this easier on everyone.

    I have one video file. The audio is in ac3 format. I still need to run the video through TMPGEnc but it does not support ac3 audio.

    The end stage is burning this video to DVD so I need to fill in the in-between steps. I've tried the tutorials but I can't seem to find the solution.

    TMPEenc will allow you to import/encode JUST the Video Stream .avi to a mpeg video stream(.m2v)alone.without sound. what everyone is trying to tell you is de-mux(seperate) the audio(ac3,pcm,wav,mp2,mp3...whatever!) Use virtualdubMod to do this..ie process Video Only..disable the audio stream....Place this stream aside...as long as it's .wav or ac3 you should be able to import this seperately into your authoring program. No need to run thru Mpeg encoder? exception: are you converting from PAL->NTSC or visa virsa? this is the only exception which will require further processing of the audio file.

    I think that's where I'm running into my problem. My program I normally use is Ulead DVD Workshop. It's a no frills app that just lets you drop videos in and make simple menus. Then you burn.

    Can you recommend a good DVD burning app that supports elementary streams?
