Stutters badly in certain scenes, can't pause or ffwd
My TV is this Sony Bravia: http://www.jbhifi.co.nz/tv-lcd-led-plas ... sku-22682/
Both the TV and laptop have wired connections to my router. Network is 100 Mbit/s, CPU is a quad core Intel Core i7-2620M at 2.70 GHz.
I'm trying to watch the BBC's Planet Earth series, from a ripped Blu Ray. 99% of the video is playing fine, but it stutters horribly when it plays certain scenes with super-high levels of detail, such as thousands of flying birds filling the screen. It stutters and pauses, and takes about 20 seconds to play 5 seconds of footage like this. To be fair, this is probably some of the most uncompressable video you will ever find:

My guess is that encoding algorithm collapses under these conditions, and my CPU hits the roof. The real reason it's a pain in the ass is because I can't pause or fast forward the video without the receiving the error 'Playback not available', with these lines in the serviio logs:
PS3 media server (http://www.ps3mediaserver.org/) can fast forward and pause these videos just fine...
So, would it be possible to alter the rendering profile to prefer crap quality for these rare scenes, instead of overloading my CPU?
And is it possible to fix fast forwarding or pause/play for these videos?
Cheers!
