I recently backed up my BD's using MakeMKV to play through my mythbox. I am able to play all of backups flawlessly except Avatar. It stutters. I should have more than enough power to play it. The machine is an i3, 4gb ram, SSD drive and the video card is a Nvidia GT610. Any ideas? I have tried SMB and NFS off my NAS just to make sure it was not a bandwidth problem. When looking at TOP during playback the CPU percentages do not seem to high. The load average is 1.1 .80 and .44 . Individual process are low, less than 10%. Any ideas?
