Hi Dodge8,
Thanks for your post and welcome to the forums. It's great having you here and getting involved in the Community.
Subtitles are mainly available on live TV channels. Some streaming or On Demand services may not offer subtitles. We promise that whenever subtitles are made available by a broadcaster, you'll be able to see them on Virgin TV.
You can turn on subtitles on your TiVo® box by simply pressing the'Subtitles' button on your remote.
If you have any further questions, come back and let us know.
Thanks,
