Wow MKV2VOB hadn't been updated in years and so I still assumed it had not. Apologies.
But it seems that it only works for those with a DTS sound system. So we can come to a compromise and say we're both right ^_^.
I'll use the optical trick if I ever run into this problem again. Last time I played the film on my laptop. Usually it would lag with a HD film but luckily The Social Network doesn't have too many motion or action scenes .
thats good to know. i have a dts setup in the living room so if i run across cinavia ill use it. ive got a 360 too so i just boot up tversity and use that when i run into cinavia. only seen maybe 3 movies or less. thats out of hundreds ive watched w ps3.
