Recording subtitles

[birdman]

Nope, you can't. Maybe it depends on which BBC-service you are?
But although the quality of the titles is less, you can also use the DVB-titles, and synchronise them the same way.

I only have DVB ones too (UK Freeview). I've just tested things out on various recordings from BBC ONE HD, BBC FOUR HD, Dave and Film4. All look fine. The Dave ones slightly out but increasing the delay by 1s fixed that.

I was intrigued to see that there are apparently subtitles (i.e. there is s subtitle stream) on the foreign-language Detective/Drama series which BBC Four shows (Sat - 9pm) but switching them on/off has no effect at all. Presumably those subtitles are merged into the video.
