I've had the VOOM channels now for nearly 3 months and I'm still finding quite a bit of stuff to watch. I consider them to be a great bargain at $5/month. I watched probably 40-50 hours from them last month, so that's about 10 cents per hour for HD material.
I would love more new material, but am more than satisfied with what I'm getting considering what I'm paying for it.
I'm surprised that people are so dissatisfied with them that they won't pay a pittance monthly fee to keep them. That sends a very bad signal to Charlie about adding more HD channels. Of course, if one doesn't watch them at all, then they are a bad value even at a low price.
