I'm sure it's not just you but it's not me. I have different issues with watchability. :blind:
I'll see some videos here that are 3 GB to 6 GB for about an hour's worth of play. My computer will not play these properly. They will stutter or pixilate. Sometimes the sound will get out of synch with the speaking. I find it unwatchable. I don't mind some graininess or colourshifting especially with vintage movies.
What secifically bothers you with non HD quality?
