VOOM has an excellent production studio and does a terrific job with the transfers and stuff shot with HD cameras. Alas, the old VOOM DBS only had one satellite and, for much of the time, only broadcast 1440 (HD-Lite) until they leased a 2nd satellite from AMC. Of course, this never happened since they shuttled the service and sold the Rainbow-1 satellite to Dish Network. Initially, some of the 10 channel VOOM lineup was full-blown 1920x1080i (like MonstersHD) and looked outstanding. Unfortunately, the channels were horizontally reduced to 1440 when VOOM expanded to 15 channels and further reduced to 1280x1080i in October 2005 when it was falsely leaked to SatelliteGuys that VOOM had a "fiber problem" with their uplink to Dish Network.
In any case, VOOM looks good because of their excellent production studio...along with the fact they showed everything AOR and never did stetch-o-vision, etc. However, VOOM has rarely looked great on Dish Network due to their proliferation of DishHD-Lite. I would love to see what VOOM looks like on FiOS TV.
