I made a disc of my copy, but I made a BD-R. If you have the funds available I suggest that route, media and burners are getting cheaper all the time. I know that’s not very helpful to your issue though…I’m honestly not sure what’s going on there, I’ve never experienced a problem like that. :-\ I’ll look into it further, you’ve piqued my curiosity.

Edit: sorry, I didn’t notice the Swedish subtitles part, that should’ve been a clue to me. I don’t know what the market for burners is like in your locale, I was basing that off my experience in the States. Do you get the same results with your transcoded MKV as well?
