Have not had any problem with VUDU using a "WD Live Hub". VUDU has the option to download owned content to its 1TB hard drive. If the network has congestion it will supplement with the hard drive data. However you must still maintain a connection to VUDU. I get Blu Ray movies on sale, usually Amazon, that have the UltraViolet option. Then go online and choose VUDU for the code option. Movies show up in My VUDU. Then download to the Hub. This way have backups on disk and Hard Drive. You can do the download and watch anything on VUDU at the same time. VUDU has a speed option up to 15M for the download. Like VUDU because I'm too lazy to get up to load a disk.
