Two reviews of my models came out within days of each other, check them out:
Xmarx Terrain review from Cranky Old Gamer
Death From Above Wargaming does great videos, both how to play and unit analysis, great stuff!
DC Bruins Battletech Videos, this guy is very talented, these are a couple of my favorites by him
A great use of footage from Mechwarrior Online (with a great track from Audiomachine)
Star Wars Short
This guy took the time to voice to text the House Davion sourcebook. This is great for those of us with limited time to read.
The guys over at Death From Above Wargaming are committed to promoting all things Battletech. This is one of their instructional videos, teaching how to play Alpha Strike. It's thorough and easy to follow.
