So, let's say I have an avi file (or some other type of video file), what's the best way to separate the audio and video tracks?

Demultiplex is when you split the video and audio to separate files.

For MPG, MPEG, VOB use TMPGEnc, select File->MPEG Tools, select Simple Demultiplex and open the mpg and hit start. To demultiplex VOBs or MPGs with several audio tracks select the Demultiplex and open the video and then doubleclick on the audio or video you wanna save. Other Demultiplexer is Xmuxer, Womble MPEG2VCR, DVMPEG.

For AVI, DivX, XviD use Virtualdub, first select File->Open Video File to open the video and to separate the audio select File->Save WAV. If it's a DivX or ASF you maybe want to convert the audio to WAV PCM then select Uncompressed PCM under Audio->Compression and be sure to select Audio->Full Processing before saving. To separate only the video select Audio->No audio and Video->Direct stream copy and last File->Save AVI to save the video.

For AVI, DivX, XviD with AC3 use Virtualdub, first select File->Open Video File to open the video and to separate the AC3 audio select File->Save WAV, virtualdub will only separate the ac3 from the video but it will have a wrong header so you must fix it. Use besplit to fix it read faq question 15 here how to do it.
