Error 'can't render one or more stream.'

[Mponetwo3]

I've been using Arpa Kolla Player for quite a while now and it's a great small player.
But now I keep getting the error 'can't render one or more stream.' with every dvd I try to play.
The only thing different is that I've installed Nero Ultra Edition v 7.5.8.
I've used clean tool from Nero to remove the entire previous Nero.
More people with the same type of error and hopefully with a solution?

you might need to unistall the dvd filters of ner.
Btw why you just not give at least a try to infrarecorder and imgburn. I abandoned nero years ago...)
