I did try it my self,went to the store and got a rf modulator and Sling Solo and it doesn't work,SlingBox can not recognize video source,I even tried connecting it with S-video cable but with not much luck:( The solution was to buy sling pro-hd:):)
I am wondering if it's possible to connect and stream regular cable to SlingBox Solo using RF modulator,meaning,your cable connected to modulator and your modulator buy AV cables connected to you Sling Box. I wonder if any of you tried this and what kind of success did you guys have..........Hope to hear from somebody soon:)
