Why route between two legacy formats instead of going straight to MP4?

Because the destination tool dictates the container: VirtualDub-era editors and AviSynth restoration chains consume AVI, not MP4. The usual pattern is MPEG to AVI for processing, then a final export from the cleaned-up result to a modern format.

Should I deinterlace during this conversion?

It depends on the workflow: for straightforward editing, yes — deinterlace once during conversion and work progressive. Serious restoration is the exception, since filters like QTGMC want the original interlaced fields and do a far better job than a quick converter-side deinterlace.

What happens to the MPEG's audio?

The MP2 or AC-3 track from the program stream is re-encoded — MP3 keeps the AVI compact, while PCM is the better choice when audio will be edited, since it survives repeated processing without further loss.

Moving MPEG recordings into AVI prepares DVD-era MPEG-2 footage for the Video-for-Windows editors and restoration tools of that period. TV-tuner captures and old camcorder discs usually motivate it, since the footage predates modern formats anyway.

Why convert MPEG to AVI?

Edit broadcasts captured by Hauppauge-style TV tuner cards, which saved everything as MPEG-2 program streams.
Run aging footage through QTGMC and other AviSynth restoration filters in workflows built on AVI.
Match the input format of dated analysis or coding software still used in labs and archives.

Tip: Interlaced broadcast MPEG needs deinterlacing during the re-encode, or every motion-heavy frame in the output AVI will show comb lines — unless your restoration chain deliberately works on the raw fields.
