Miro looks nice and fits in with the Mac aesthetic quite well. It also has a list of impressive features. It offers "6,000 free internet shows and podcasts" and boasts a large amount of HD content, downloaded directly onto your Mac. Miro also downloads torrents and supports the following video formats: Quicktime, WMV, MPEG, AVI, XVID, among others. In addition, Miro offers various video sharing websites, such as YouTube and Google Video in HD. With all of these features how can it be bad?
Well, for one the interface is not very user friendly. There are a limited number of ways to browse content (none of them alphabetically either). You can search for videos, but that only works if you have something specific in mind. Also, the content is not that mind bending. All of the shows Miro offers are just pulled off of sites like Hulu. I can watch the same thing with FireFox, so why do I need this software? The same thing goes for videos from YouTube and Google.
Also, since all of the content on Miro is free, most of the 6,000 internet shows and podcasts aren't anything to shake a stick at. Who cares? I don't.
As for the various video formats supported by Miro, it's not that important. VLC players support more, so there is no need for MIro if you have one. The same goes for the torrent download. Vuze is user friendly and works just as well. Also, Miro steers clear of violating any copyright laws with its free content, so why include a bittorrent client? Not all torrents are illegal but many are. This just seems a little hypocritical to me.
