So, recently the anime shows I've been watching are being shown in HD intended for 720p (1280x720). XViD encodes are available in avi format and play okay, but a lot of uploaders are encoding them in mkv with subtitles. Now the issue is that the video slows down, so the audio doesn't even sync. I came to a conclusion that my dual G4 is showing it's age. So, after 4+ years of service, I'm thinking about upgrading. At least I got my money's worth instead of having to build a new computer every 1 1/2 years with a PC. Anyhoo, would a Mac Mini be sufficient to play HD videos? Or would I have to get a QuadCore tower? I'm a graphic designer and I already get by with my 17" Powerbook and my dual G4. I don't really do any video editing on Final Cut Pro or do anything crazy, but I also wouldn't mind having the power to do so if it's cost effective to plump down $2500 for a new tower. I'm just doing my once in every 5-years computer upgrade, I suppose. Any suggestions or insight would be great! Thanks!
