The best thing I can say to do is go their website,
http://www.voom.com. They have about 30 channels that play HD, altough most of the old movies on the cinema10 channels a not filmed in HD. The fashion model channel is awesome, women all day walking up and down the runway.
Overall, I am very happy with the service, give it a try for 1 month and if not happy cancel, no contracts. I rent the box from them for $10 a month plus service.
