Access Violation while opening AAC file

[tengo6dedos]

Hello, i have this problem i think may be codec related. I extract a AAC audio from an mp4. The extrated AAC throw me Access Violation error multiple times when i try to open it. I tried extraction with TsMuxer and YAMB but with same result. Note that the audio of the original mp4 plays just fine, also QuickTime can open it but only by auto transforming to mov?


This is the error:

I use winxp, the codecs i have installed are Mastroska Pack and FFDShow.

Im clueless, any help appreciated

I did a simple workaround. I just opened the mp4 in virtualdub with avisynth and "Save Wav..", and the .wav audio output ends fine for what ever need.
