You really aren't specific enough to have us help you.
First off mounting a PDP on a load bearing wall is probably the most secure installations you can have. As for feeding the panel power and signals you will have some difficulty. As 3Series points out insulation is do-able and here is a reference
that might help you.
Blocking however is called different things in different parts of the country:
Some places refer to blocking as sound absorption (i.e. sound blocking) material a PVC with a sand mixture - which causes no problem for running power and signal cables.
Sound absorption designs can also call for two sets of studs, offset from the base. So that each side of the wall is attached to a different set of studs - this also makes for nice load bearing application. It is important to find the studs to which your side of the wall is attached to or you may crack the drywall when attaching the mount. Again this still allows for enough space to run power and signal feeds. It's just half the normal space about 8" instead of 16".
Blocking could also be known as material placed at the base of the floor to prevent the migration of fire (i.e fire blocking) between floors. Again this shouldn't provide much difficulty to running the cables.
I've also seen the term used for the placement of 2x4 remnants offset to each other as if assembling a staircase out of blocks up each side of a small space in a load bearing wall. Couple this with insulation and it will be close to impossible to feed cables through the wall. In one case after playing with this for several hours I got so dumbfounded that I ended up opening up the wall to route the cables and even then decided to pick another section of wall, because if I ever had to replace or add future cables I determined that it would have still been too problematic (too many turns and too many places to catch cable and not enough room for conduit.)
Then there is blocking associated with installing and attaching a wall between two joists as you can see here
if you're cables are dropping from the ceiling this does not create severe problems unless the blocking material is exactly where you want to run the cables, but this should be easily determined with a pilot hole from above.
And I imagine blocking could be describing something else all together.
