If anyone is really that desperate for Viacom channels, Dish has some of the channels in its lower packs. For example, in Dish's $14.99/month package, CMT, Comedy Central, and MTV2 are included along with other channels (in SD) along with locals (in HD where available). Usually, this is used for retention, but as of recently it is advertised on the Dish site. FMI:

Also, in Dish Family, Dish has TV Land, Nickelodeon East, Nickelodeon West, and Nicktoons along with other SD channels along with locals (in HD where available). FMI:

I believe that Dish Family is the minimum American package for the $10/month Blockbuster @ Home package with one disc at a time. It looks like those with Dish Latino Basico may add it, too. Blockbuster @ Home includes Palladia, Centric, and Logo. Epix 1, 2, and 3 are also included. There are HD channels in this package. FMI:

In addition, according to Dish, Comedy Central HD, CMT HD, Palladia HD, and Spike TV HD are in Dish's $34.99/month Dish America package.
Although it may seem obvious, I should also mention that an HD receiver is needed for HD channels.
If looking at some of the higher packages, Dish's $44.99/month America's Top 120 (along with HD 120 Free as well) package includes CMT, Comedy Central, MTV, MTV 2, Nickelodeon East, Nickelodeon West, Spike TV, TV Land, and VH1. According to DIRT, Palladia was recently put back in America's Top 120, but I cannot confirm that. FMI:
