Hi, I'm a Windows user and I recently bought a Mini C2D 1.83 to plug in to my LCD TV. The Mini is running Leopard and it's connected to the TV via DVI, 1360x768, millions of colors, the works. Everything's set up with QuickTime + Front Row + iTunes + DivX + AC3 (AC52). I dropped aliases for my Lacie NAS drive in the 'Movies' folder so that I can access my movies via Front Row. So far so good. It's a slick setup and I'm loving it. There's just one headscratcher (and tentative dealbreaker) that bugs me... why does all video look like crap? The same movies that looked gorgeous when played back on the same TV from my retired WinXP media machine, now look like bad YouTube videos on the Mac. All dark areas are blocky as hell -- what's supposed to be black (or thereabouts) looks more like 'Turd Tetris' (a bunch of huge squares in various flavors of brown). I thought it might be the DivX codec so I experimented with the Deblocking and Sharpening settings, but it still looks just as blocky. I tried to skip DivX altogether and ripped a few of my DVDs with Handbrake. I went for pretty hefty settings, using H.264/MP4/AAC, an average bitrate of 2500 kbps, 2-pass encoding, Anamorphic (PAR) and the movies ended up around the 2 GB mark, which means they should look a heck of a lot better than a measly 700 MB DivX rip. Nope. Still getting the turd Tetris effect. Gave up and went to Apple's movie trailer section to check out some fat HD trailers... but no. Still getting those pesky color blocks. Heck, even straight DVD playback isn't up to scratch, it looks kinda grainy compared to my hardware player. This only applies to video playback. Any and all Leopard desktop graphics, iPhoto galleries etc, are presented in glorious 32-bit with ultra smooth gradients etc. What am I doing wrong here? Obviously you guys aren't putting up with such p*ss poor video quality in Leopard compared to a stinky old XP system, so I must be missing a magic switch somewhere. Anyone?
