Some quick experimentation with their public API shows that they don't provide roku compatible urls. It is possible to dig through their API & JS and find references to possible roku compatible urls, but if I try to look them up, they appear to be looking for a "content-partner" parameter. I'm don't it is possible through their public API to build a roku channel. That said, someone may be able to develop one if they contact dailymotion and work with them directly. I don't have the time right now to do so, but perhaps in a few weeks.
