Actually it's pretty hard to get that "steady supply of new videos" happening. Between the number of really dreadful videos that we don't want on the channel, seeking out new artists and having to constantly hound the various labels to send us stuff, it's a pretty constant challenge. However, we did recently add six new blocks, and we're working on more.
I've been watching LinkTV on DirecTV for about 5 years now. I think I have seen most of the music videos a few times and some more. Yes, there are some new premieres every week but the bulk of the music videos are repeats. They're nice and I have many favorites but in 5 years you'd think there would be a steady supply of new videos added all the time. I wouldn't want all the old ones to go away; just have some new ones being added all the time.
