There isn't much we find wrong with Connect360
, the $20 media sharing app that helps your Mac play friendly with your Xbox 360. In fact, that solution is arguably preferable to the official Windows Media Player solution in Windows, so the newly released Rivet has something of an uphill battle to gather Mac OS X mindshare.
Luckily it has two advantages: unlike Connect360, Rivet replicates "the entire folder structure" on your Xbox so there will be "no more scrolling through a huge, flat list" (great if you've got a lot of music and movies); secondly, it's $1.05 cheaper.
