Hello - have xfinity x1 and recently bought an M1 with the suggested converter box. So i have hdmi out from x1 - into the converter - component out to the M1 - and hdmi out to my TV. I cannot get 1080p on my TV... (should just pass thru the converter right??). So i bought a splitter, to hdmi into the slingbox and the TV...and one of the outputs would not work. So, i bought a switch (hdmi in - then A or B out). The M1 will not work with the switch!! Ideas why? Fix ideas? Thanks.
