[u][b]missing audiostream half way the captured avi file[/b]

[miki1]

I'am trying to convert an home made avi to DVD.
First I capture the file from my DV camera ( JVC GR-D20E) = 50.56 min--> 11GB with fire-wire. Used capture program is WinDv and DVIO.
If I analyze the captured AVI file with VirtualDub then I get next info:
Video lenght = 50.56 min and audio length is only 31.23 min ?
That is quite strange ? Video and audio have not the same length.
I tried 2 different capture programs ( WinDV and DVIO ) but the result remains same.
If I play the file on mijn DV camera then is the audio OK.
After the capturing the file is the remain space on mijn HD 13 GB ( it's a 40 GB HD ).
If i try to play the captured file with Virtual dub or real player then I miss the audio stream after 31.23 min. First 31.23 min
Converted DVD file has the same problem. Used convert program is Avi2dvd or TMPGenc and during the convert i have no errors.
HELP HELP HELP
P.S See the avi file information.

I have foud the problem ( I think )
On one DV tape i have record the first 30 min with 12 bit audio ( 33000 Hz )and then I have changed the audio setting on the camera to 16 bit audio ( 48000Hz ) and then I continue the recording with the new audio settings
Dumb !!!
So I have to capture the file in 2 pieces ( one piece with 33000Hz audio and another with 48000Hz )and then merge the files to one avi.
I have already captured the 2 pieces, now I have to merge them.....
