I would suggest Pot player as backup for u ...
It will give better compatibility than MPC while playing partially Downloaded Files and corrupt ones .... Also wide ranges ... Almost a clone of MPC ...
The Clarity Wise and Audio Wise its excellent - It also has perfect hardware acceleration than MPC never gave me a glitch even in 1080P ...
I consider Even MPC a 10% less to Pot player ...
64 bit also avail ...
Though it's less popular - Don't think the other way ..
You won't regret .. You won't need any other ...
Yeah I have tried in WMP it played smoothly even in KMP it played well....
so the conclusion is VLC uses its own inbuilt codec pack whereas other players
WMP,MPC,KMP & GOM Player uses external codecs.
I would suggest
Pot player,MPC,WMP KMP & GOM will do Fine .. You Won't need any others ..
