I think I've uncovered a problem. I have an IPTV box that outputs 720p60 to a Slingbox 350 on my LAN. Firstly, using the Sling web player with IE10 I can get a smooth picture from this Slingbox, confirmed by the stats (ctrl+click) reporting 60fps. There is one glitch whereby sometimes when I first connect it only gives me 30fps and I have to switch to a lower setting (like 'Better') and then back up to Best (HD) to get 60fps. However, with SlingFront it seems to be impossible to get 60fps. To give this some context, if I put my Sky+ HD source, which outputs 1080i25 into a Slingbox 350, through SlingFront I can get a nice smooth 50fps picture. Also, if I switch my Sky box to output 720p50 then SlingFront at least attempts to stream 50fps (ie the stream info reports 50fps), although because the Sky box is remote I struggle to get enough bandwidth. So there seems to be an issue with displaying the stream from the 720p60 source. I've also tried the same test on three different machines and in each case IE10 can show the stream in 60fps, but SlingFront refuses to go above 30fps. In each case the bitrate shown in SlingFront is comparable to that which IE10 achieves.
