Jessica S, you can use your iPhone (and maybe other smart phones?) for the remote..or order one from amazon?

or email or do a live chat with the Roku website?...I'm sure you can order one from them???..or they can direct you where to find replacement?..
I have called Roku with several issues(usually not theirs)...they are SUPER HELPFUL...even if my problem was with the channel itself...
KF---We have 1 Roku box, but have bought them for gifts for other ppl...there are enough free channels with variety that you can never watch it all...and are always adding more..cable and pay per view is not necessary...unless you just want it?
purchase one time(less than $100 for the most expensive HD only set) and have forever tv of some kind without a monthly fee..plus you can do the pay per view thing or individual channels if you prefer?...but we find so much free stuff(along with netflix) there is no need to spend a lot of $..plus if you do amazon prime, you have access to their streaming movie list?
