|I have just bought a second hand Acer Revo RL70 with BD.|
1080 Playback is juddery.
Both BD and HD files are problematic.
i Tunes 1080 playback is the worst. I can only play SD i Tunes movies.
Given it had a dedicated BD, I am very surprised by this lack of performance in 1080p playback
I have made sure that nothing else is running and all of the drivers are up to date.
