720p and 1080p videos are jerky and not synchronized with the sound. Sound often stops after couple of seconds. Tried playing with VLC, SMplayer and Kodi Media Centre. Same thing on YouTube when playing HD videos.
HTPC is from 2008, until recently had Vista on it, but with Ubuntu as only OS works much better.
I have following configuration: MB Gigabyte MA78G-DS3H (full HD 1080p and Blu-ray play back), CPU AMD AM3 Athlon II X2 250 and Gallium 0.4 on AMD RS780.
I am a complete beginner, searched internet regarding this topic and found couple of possible solutions, but nothing worked for me.
Will appreciate ideas what to try.
Thanks
sudo apt-get install ubuntu-restricted-extras
should do the job.
