I have read all the forums on all the solutions. Went out and bought the following:
Farsail 1x2 HDMI Splitter
Portta HDMI to YPbPr video converter
I have the HDMI from cable box running to splitter then one HDMI goes to TV and the other goes to Portta video converted where I convert the signal to Component (YPbPr) which then runs into Slingbox350. Unfortunately this does not work. I have even tried changing output resolution to 1080i and 720p and still it is not working. Very frustrating. Any thoughts please let me know, thanks!
