I'll be getting my new iMac (and my first Mac) between now and 24 December. I know Perian is no longer being developed (hence I assume it doesn't work on 10.8), besides Flip4Mac, xVid 9, is there anything else I need to install for QuickTime to support my video files? My files are in all different formats, xvid wmv, avi, etc. Chrome and Firefox are great but I would like to use Safari as my default browser, do I need to install Flash for Tumblr/YouTube? Are there any other Safari/QuickTime plugins that I should install? I've done the Google searches etc., and there are hundreds of work-arounds, how-to's, etc., and most of them are old. I'm hoping someone can tell me what to do (as install complete video playback) from the moment I plug my new Mac in. I'm an old linux user, and I'm happy with VLC on Ubuntu, but I would prefer to use the in-built apps such as Safari/QuickTime as the defaults. Any help or guidance would be greatly appreciated. Thanks.
