    Hi...I have done my capture...... processed it in Vdub and encoded it in
    TMPGenc....I now have a 700mb mpg file ...BUT only to find the audio needs
    amplifying .....I have read there is a normalisation filter for TMPGenc but
    its certainly not in my version....
    At what point should I have amplified and is it possible on Vdub or TMPGenc
    ...and any tips on amplifying the audio at where I am at now would Be
    Appreciated ...

    Thanks Ron.

    Setting -> Audio tab -> Audio Edit -> Setting -> Normalize
    You should use a VU meter to set the correct audio recording level
    just before you start capturing. This free VU meter works for me:

    Any audio editor will do it. Cool Edit, Sound Forge, etc.
    Audacity is a free audio editor: http://audacity.sourceforge.net/
    If necessary you can extract the audio from an AVI file with VirtualDub
    or VirtualDubMod: http://virtualdubmod.sourceforge.net/

    This is probably the easiest way: use TMPGEnc (File -> MPEG Tools)
    to demultiplex your MPG file, then normalize the audio file while
    re-encoding it with TMPGEnc (ES - Audio only) and then multiplex audio
    and video again (also with TMPGEnc's MPEG Tools).
    But there are plenty of other possibilities.
