Problem PCC Balance + PPPOE Server

HI
i am a beginner on mikrotik
i have to connect to WAN-s gateway (192.168.0.1 & 192.168.1.1) and three LAN-s(192.168.35.1 & 192.168.45.1 &192.168.55.1) i actually have configured it simple with both gateways at IP-> routes but i have some problems during work and the main problem is for videos on youtube for example they stuck and need a page refresh to be loaded.
i dont know if i can use the PCC technique , i don’t use pppoe at all.
thanks in advance
