I personally agree with rossi the ok button be left as it is but use another coloured button instead for context-sensitive options.1: When navigating the epg pressing the OK key would now either zap or zap and exit the epg, I propose a context menu popup with three or more options of Watch,Record,Add Auto Timer, maybe other options like TVDB and TMDB, IMDB perhaps
You can already change the assignment of buttons via menu settings as I've set, on my solo2, red button as PVR (as well as the dedicatated PVR button I have) and < > as channel up/down. I'm not sure if they work from within EPG listings though or if it's whilst watching TV (live) only!!!2: Add an option to access recordings via the red button instead of the imdb function which is only good for movies really and not general tv programs, at the moment the only way of accessing recordings or pvr is through the dedicated pvr key.
If it's the latter then it would be nice to pick/choose what each coloured button from the EPG can do rather than having red for IMDB, etc. I do use, and like, the Blue for AutoTimer though.
I don't use IMDB but of course some may do.
