I have a PACE TDS855 sat.rec. connected to the TV via HDMI and Slingbox 350 via SCART output (only option)...it works fine in all combinations EXCEPT via Chromecast, where I get the 16:9 picture squeezed into 4:3 format. Searching the web I can see I'm not the only one, but only hint I have been able to find is to select HD override on a particular box and a feature mine does not have. I have tried all combinations of HDMI and SCART settings without any luck. Using the same Chromecast from any other App on iPad, iPhone does not give the same problem.
Any ideas or something that will be fixed in upcoming release?
