Just set up a Slingbox 500. Large Network with lots of devices. FIOS 150 mbs so should not have bandwidth issues. Old Slingbox Pro HD use to work fine. Any ideas what problem might be? I am connected from my Moxi DVR to Sligbox to TV. When picture cuts out on Slngbox, same happens on TV. TV picture comes back when I disconnect Slingbox. Same result when I watch on PC or on iPhone. Tried connecting Slingbox wired and wireless. Same result. Thoughts?
