[mythtv-users] Cycling through available subtitles

[Ian Evans]

I have a key on my remote set to send a T to bring up the subtitles for
when my mother-in-law is over.

The T turns the ATSC 1 subtitles on, which is good 99% of the time, but
today I just noticed that an old movie recorded on retro OTA channel
"Antenna TV" had the subtitles in VBI.

For WAF benefits, is there a way for 'T" to cycle through available
subtitle methods before turning off? Right now it's just ATSC CC on/off.

Thanks for any advice.
