Virtual Dub not recognizing freezes

[phs]

I have an AVI video file that freezes when I try to encode to MPEG with TMPGEnc. I have run it through Virtual Dub which picks up some of the freeze points but after editing and deleting the dodgy frames the resulting file still freezes in TMPGEnc and the MPEG result plays upto a point with the video, freezes, but the audio continues unaffected.
The original AVI seems to play perfectly fine past the point that the MPEG freezes on so is there any reason why VDub is not picking up on these frames or can settings in TMPGEnc be changed to decrease sensitively to allow it to skip past these points?
Any help would be appreciated.

i have had this problem before, especially in the area on where v-dub mp3 freeze searches the bad frames , but when i encode (only about 10% of the time), theres a freezed frame..is there any other tools in the warez section can help to alleviate this...i know demuxing also helps..also...ive had a problem where a compltete file plays on my comp , but after a while the picture just cuts out lesaving the sound...does anyone have any solutions...holla
