Lol I haven't seen a red record light on an STB in a while .
Red ment an issue on the beta test fios IPTV STBs and on the D* genie 2 system there is a green light and blue logo meaning on/working. I think a yellow when there is an issue . On the server there is 2 solid green lights when working.
I could be wrong but I think cox/xfinity client boxes don't have a red light...
I do remember years ago the R15 or HR20 had a red record light lol
From LED clocks on cable /telco STBs to no red record lights... my overall summary is evey STB and company is different and things change .
i know its not "much" but so far there has been a 4K event every day in June . (until the 20th) . and to my knowledge only Fox Sports events have been available streaming. i don't think Peacock offers 4k so i doubt the US open will be 4k (streaming)
