34 is Dish Pro and has 4 outputs and feed throughs. 33 is Dish Pro Plus (supports dual tuner separator) with 3 outputs. A DPP33 should replace any single DP34 just fine unless you're feeding 4 non Dish Pro Plus tuners. (There's no such thing as a SW33 or SW44)
There is no such thing as a SW44? You might want to double check that
.
i have 2 boxes one 722 and one old 301 the 301 has stoped getting signal i have 3 lines coming in 2 for the 722 and 1 for the 301 from the dp34 so i think its gone bad. the forst 2 lines are working fine but not the 3 and 4 of the dp34.
i dont know what lnb i have they are on top of a building so i dont want to go up. should i buy another dp34 or buy the new dpp33 and also get rid of one line.

actually there is...there are SW42,44,64
42...2 inputs, 2 outputs (basically its 2 SW21 switches)
44...2 inputs, 4 ouputs
64...3 inputs, 4 outputs
each satellite takes 2 lines from LNB to switch
