I did the same. I had one moment where it took a while to load, but I was also doing some things on my computer, and as I've said, I don't have the best internet. I may need to upgrade.
But I can't recommend this enough. I've loved my experience with Vue so far.
One odd quirk is that when you add a show to "My Shows" (their version of DVR), it adds the whole series. So, last night, it showed me ALL the football games they had in their cloud. To go back and rewatch, I'll just select the FSU-NU listing.
But this morning, I went to record today's episode of a CNN Sunday show. A bunch of previous episodes were listed, and today's, even before it officially aired. It's GREAT.
