Comment (by Matt Marjanovic):

 > What is interesting about your setup is that it is using the intel iHD
 driver. Is this the default on your system or have you deliberately set
 that up?

 I had no idea two drivers even existed, so that must be the system default
 (debian bullseye/testing).  Both drivers/packages are already installed,
 though, pulled in by `va-driver-all` which itself is recommended by
 `libva2`.

 > Could you install (if not already) and compare playback between the 2
 drivers on your system?

 I tried out i965 now: as far as the menu misbehavior goes, the i965 driver
 is behaving the same as iHD; log file attached.

 > So I can't currently reproduce this - will need to cast a net for a few
 extra DVDs to try (haven't bought any new ones in years).

 You are welcome to try https://www.mir.com/truncated-groundhog.iso --- it
 is the first 282MB of the disk image, i.e., the menus and nothing else.

 > Testing here, the iHD driver (from the intel-media-va-driver package)
 does not support VAAPI post processing (for deinterlacing) and has a few
 rendering oddities that I don't see with the i965 driver (from the i965
 -va-driver package).

 Hmm, what kinds of oddities?  (Curious if it is anything I unconsciously
 experienced.)
