I have created an avi file from an rm file using tinra and when attempting to sync the audio, using the "Change so video and audio durations match" option, it just doesn't.

It displays the framerate it is going to use next to the option, and it has 1.5 fps (or thereabouts) displayed. If I manually set the framerate, it should be about 8.5.

My avi file is 30 mins long, the rm file is 22 mins, so why does virtualdub think it should set the framerate so low?

Thanks in advance
