I use them as a space indicator. My stock tivo 3.1 seems to very regularly and timely update itself recording suggestions when i have watched stuff and have free space. However my 6.3e 2 drive machine hasn't recorded a suggestion in over a day now and there's definitely space. (this lack of recording is a very regular event) So this means i think i have less space then i do of course. Yes we keep both tivos full now with the new season upon us. Today i checked. There are 4 suggestions under the pick programs option so does that mean those will record, absent conflicts? And why doesnt tivo record all the stuff i have 3 thumbed up? A long time ago I literally went thru the weekend shows (and of course many other series during the week) and 3 thumbed a huge amount of them. For example, right now if you go to guide and scroll down through the channels, i have no less than 20 shows that are 3 thumbs and yet no red light is on and nothing being recorded. I can only assume that 6.x handles suggestions differently than 3.1? My last clear/delete SP/wl etc was months ago so that shouldnt be the issue.
