Agreed on the ads, which are thankfully only on the website and not during playback. I don't have any issue with unsynced audio or buffering. The TNG episodes only appear crappy if you full screen it, but NTSC resolution is crappy anyway. The Enterprise episodes are terrible quality because those were all filmed in HD, so of course. It's no worse than watching just about any random copyrighted infringed video on Youtube.

It's the modern equivalent of staunch's dad's dubbed copies.
