I downloaded a .MP4 video for the PSP
It have M4Vxxxxx.MP4 and M4Vxxxxx.THM
When I play it on the PSP, I could barely hear it even though it at max. So I was trying to increase it using another program. Here's what I did.

1. I extract the Video and Audio sources from the .MP4 file, it came out with M4Vxxxxx.cmp(Video Source) and M4Vxxxxx.aac(Audio Source)
2. Then I use Goldwave to increase the M4Vxxxxx.aaC volume, then I save it as M4Vxxxxx.mp3
3. Now I mux the M4Vxxxxx.cmp and M4Vxxxxx.mp3 together to become a whole file again.
4. Put in the the psp, the video play fine but there are no audio.
So this method doesn't work.

Is there any other alternatives ways to increase the volume? I know I could just encode the whole video again using other converter with Volume Boost, but it take too long.

Thanks.
