Search for the apps in the play store using your Google TV now you know the names of them +Sarah Grady
as if they show up in a search using your google tv maybe you can try loading them then. I know I have the 32" Sony LED GTV - NSX-32GT1 and I don't remember it being able to load many apps do to it being a first generation Google TV.
I never sideloaded anything on it either, but I do remember a clock and timer built in to the tv. I think if I remember right you can do a search on your google tv for the word "clock" to find the clock app and "timer" for the timer app I believe.
Don't use the quote marks when doing the search with your google tv.
I don't remember the calendar app so maybe +Matt Lane
