[mythtv-users] USA OTA - interlaced?

[Matt Garman]

Is there a way to tell if a given recording is interlaced or not?
FWIW, I'm in Chicago, IL, USA.  We record the national networks,
primarily FOX ("WFLD 32").

I ask for the following reason: a while ago, I started experimenting
with using Intel (Sandy Bridge) graphics, so I could lose my
power-hungry Nvidia card.  During initial testing, I disabled
de-interlacing in my playback profile.  And to this day, I still don't
have any interlacing enabled, because everything plays back
beautifully.

So either I am recording progressive content, or my TV (Panasonic
TC-P65V10) is doing the deinterlacing for me.

Thanks,
Matt
