Is the speed of your internet 30mbps on the PS3 network test, or just on your PC?
You computer beats the hell out of mine, yet I play 1080p 18gb DTS movies with subtitles just fine... so there is something there for sure that isn't right on your end.
Is the Laptop of powersaving mode?
What type of router do you have? It might be slowing done the connection enough to make movies lag...
Wireless is not the way to stream any HD movie. Even being just 1 room away from mine, it can't stream anything above DVD quality without having issues. You must go wired for 1080p quality.
Youtube lagging is either an issue with the speed your ps3 is connecting to your router/internet, or just youtube in general. It's been rather slow for me on certain ones as well.
Also, are you using either PMS or UMS to stream to the ps3? If so, make sure you disable subtitles, as this can sometimes cause issues with buffering. I also recommend setting the amount of cpu's to double what you have. I have a dualcore as well, but have UMS and PMS set to 4 cpus, and it seemed to actually help it buffer faster.. might be just a placebo affect though.
Some movies can eat up the buffer and will also just require you to pause it for a little bit to fill up the buffer. Then it will give your computer time to buffer more as it plays.
