2 halfs of a movie same codec but cant decompress the 2nd 1

[Icu2]

ok well this is the story...I have a divx file that has 2 halfs.. both halfs have audio that after running throught gspot has

Name: ac3 (0x2000) Dolby Laboratories, Inc
Stat: 2 comp codccs installed
Bitrate: 448 kb/s (5 ch) CBR
FS:48000 Hz

Now what im trying to do is decompress the audio to PCM. Im doing this through virtualdub I can do this fine on the first half but the 2nd half i get a message that says " No audio decompressor could be found to decompress the source audio format" now this really has me stumped coz they are both the same codec.. and same movie it has just been split..

the final result is join these halfs together so it will make one divx file instead of 2. I have tried to use Virtualdub using the appened avi segment and i get the same error. I have tried to use AVI MPEG RM WMV Joiner and it says that the audio streams have differant data formats.

I thought ok just decompress the audio..join them..recompress.. but i tried that and i got the error above in virtual dub.

i really dont konw why this is happening coz its the same file pretty much. It isnt a Vbr and yeah i dont know why this is happening.. if anyone else has had this problem and could help me fix it that would bgreat because i really dont know what else to do. i just dont understand why i would b getting this when they are both the same movie encoded at the same time same settings just been split.

thank you for you help

which done incorrectly could cause a corrupt header or similiar problem.

Anyway, if you want to keep the AC3 audio, open avi1 in vdub and then 'append' avi2. Use direct stream copy mode to extract the audio to 'avi.wav'. Rename this to 'avi.ac3' and run it through ac3fix.exe to get avi2.ac3 which should now be a valid, joined, ac3 audio file.

Hope this helps

yeah thank but it still doesnt work it still says the same message "No audio decompressor could be found to decompress the source audio format"

so do u think this could just b a corupt file etc? coz it runs fine and i can burn it 2 a cd and copy it 2 another location.

If you have ac3filter installed, then try opening the avi in goldwave and saving it as a wav file from there.
