This player software is useful when you want to quickly view your captures with double-rate deinterlacing. VLC is useless for this task unless your captures happen to be Bottom Field First, because its field order is hard-coded when the source file doesn't specify it (and AVI carries no such header info). Apparently the PotPlayer developers actually have a brain in their heads, offering the option to toggle this.
If you want to follow along with the exact file I used to take the screenshots, it's from
mparade.
Just a few simple steps
1. Open a file and observe the normal ugly, combed playback we expect from interlaced AVI files.

2.1 Right-click,
Video -> Deinterlacing -> Always Use.
2.2 Right-click,
Video -> Deinterlacing -> De-interlacing settings...

3. Change the
Software Deinterlacing Method in the dropdown to one of the
2X options. My personal preference at this time is
Motion Adaptive(2X Frame).
* If your capture device is one of the few that uses BFF, set this dropdown to match. There is also an Auto option that
I suppose tries to guess the field order automagically, but I assume there is a reason this is not the "Recommended" option from the developer.

4. Play forward and give it a second to kick in, or start playback over from the start of the file. Observe the nice, smooth motion and lack of combing.
* If motion stutters back and forth, change the
Field order dropdown from step 3.

5. Compare the various software 2X methods to Hardware Auto. To enable hardware deinterlacing for AVI playback, you must toggle the dropdown labelled
When an interlaced flag is not detected to
Use Hardware Deinterlacing.
My results with Intel hardware deinterlacing look softer than Motion Adaptive, though it does avoid the artifacts left behind (stray interlacing from the motion mask). So it's personal preference. It's easiest to tell the difference between these two screencaps if you open them both in new tabs and flip back & forth between them.

Final note
Remember that if you want to play back ordinary progressive files in PotPlayer after this, you will have to switch back to Auto from Always Use. The quickest way to do this is to tap
Ctrl+I twice to toggle your way back through the
interlacing modes, rather than opening up the multi-level context menu.
