I have the BBC Planet Earth documentary, but I can't play the videos on my computer without significant lag, and they don't render properly (green squares and stuff everywhere) on my HDD-media player. How would I go about converting them to, say 720p? I run both Linux (ubuntu) and Vista, any help would be greatly appreciated. https://192168o1.com.br/ https://19216801login.com.br/ https://logintplink.com.br/
