You might wanna see these: Might I suggest if you don't want rp files, then you block those extensions via both the shared extensions & Tools>Options>Filters>Keywords & add the ekstenshons you don't wanna find or download

I suspect your problem is RP wants to be your main default player & thus takes over icons control, & player rockontrollability.

Thus make your other player for "all" video types! Cat biscuit please!

Unlike others I expect to be fed!
