The best is
I'd experimented all of theme and finally i uses most of time DVBDream. It's freeware, had no pretention , developped in communoty and very stable.
ProgDVB is less and less stable specialy the last version and more in the freeware version.
DVB Viewer is good too but not "ergonomic" as DVBDream can be with his full of favorites and thematics .
