Hi All,

Untill recently i was able to use graph edit for converting any AAC audio to AC-3. Primarily because AAC audio in an AVI/TS/M2T file is somehow not played properly by my PS3 , which is my main media machine tio stream any kind and every kind of playable content.

The AAC demuxed from any MKV is simply to be dragged and dropped in the GraphEdit work area and it would construct a filter graph for the audio decoding chain, which I can later amend manually by ffdshow-directshow filters to read and output the AAC file into an AC-3 file.

Everything was working fine, when suddenly after quite sometime i needed to convert an AAC file and when dragged and dropped to GraphEdit, it displays an error as shown in the attached image file.

Can anyone guide me as to what am I doing wrong. I have not uninstalled any of the previous directshow filters and all the settings are intact. I guess i may have installed dBpoweramp for testing purpose but it should'nt make any working program go haywire.

Any ideas and help is highly appreciated.

Regards,
Myself.
