The remote for my Roku quit working. The remote I have is a RC12. I've tried all the internet fixes (batteries, repairing, shutting down everything and restarting, etc.) but it just doen't work. Right now I'm using my IPhone as a remote but I'd rather just buy a new remote. I understand the RC12 is RF and most of the available replacements seem to be IR. Can someone recommend a good source for a replacement that isn't shipped from China?
