The teletext is very good, massively quicker than my old Pace OND box.
The pages of the digital text are very different in layout but carry much the same information and you usually get a small tv screen in the corner playing the current program. One improvement over analogue is that multiple pages can be accessed as and when you want instead of flipping over at a regular rate.
You can only record directly from the broadcast streams from the internal tuner. It would be a good idea to allow external recording but you can't have everything.
Only Tivo or one of the DVD/HDD recorders (somebody is bound to argue that these are not PVR's) from Panasonic, Sharp, JVC etc, but they don't have a program guide. The new Philips DVD/HDD recorder due out soon will have guide plus.
