Convert AVI to DAT

There are certainly tools available that are capable of reliably converting Audio Video Interleave Files directly to VCD Video Files (.avi to .dat conversion), although the DAT file type related to the VCD video format is somewhat outdated.

It appears that your best bet is using programs, such as SUPER or 4Media Video Converter, which permit users to import AVI videos and re-save them in DAT format.
