i tested closed-captions this morning and unfortunately they do not seem to
work. the frontend displays an icon meaning the recording has closed
captions (no idea how that's determined!) but no subtitles options in the
menu during playback and hitting t (toggle subtitles) has no discernible
effect.

this is not a deal breaker for me as i RARELY use subtitles but for some i
concede that it may be! i am happy to do any other testing in this regard.
subtitles DO work on my other mpeg2 recordings.

i'm also on mythtv v0.27.4 so things may have changed in newer versions or
0.28. i'm planning to upgrade to 0.28 when i have two weeks off at the
start of june.

for the file size questions i only did one recording to see if it worked so
not really conclusive but i got about 2GB/hr which is 1/2 or 1/3 the file
sizes i typically see with mpeg2.

best regards,
