Anyone have any good tweaks/apps that can be installed onto the ATV after JBing?
I use ATV2 mainly to show my iPhoto photos and home movies on the big screen. Very handy since we have young kids and take LOTS of photos and home movies of them. Also handy to rip their favorite DVDs, import into iTunes, and have those shows available at the touch of the remote button.
As for jailbreaking: I finally did that a couple of months ago.
-Plex pretty much just replicates what iTunes does: makes videos on your computer viewable on your apple tv. . . I have it installed but don't use it because I don't see why it's any better than iTunes. *shrug*
-XBMC seems a bit better than Plex to me since it is apparently more customizable. If you download the "Bluecop Repository" in XBMC, you can watch Hulu (both Hulu Plus AND regular free Hulu) on your apple tv WITHOUT COMMERCIALS! This is the best benefit of jailbreaking, in my opinion. My wife and I are about to "cut the cord" on our satellite TV service, and having Hulu without commercials on the Apple TV makes that easier since it gets us some cable shows on the TV without cable/sat service.
-Airplay is fantastic IF YOU HAVE OTHER iOS devices. This is because, in my opinion, it is easier to navigate an iphone or ipad with your fingers than it is to navigate (and especially to "search") the apple tv using a remote. We often search for a youtube video or a radio station on our iphone, then just hit the airplay button to send it to the TV. And the audio from most apps (and the video from some) is airplay enabled. I use it to listen to "This American Life" radio show episodes, streamed from my iphone app to the the ATV2 via airplay. And after iOS5 arrives, you can mirror anything on your iPad 2 screen to the ATV2. . . this includes games and those TV watching apps.
-This macrumors forum post suggests you can now airplay most videos viewed on safari on your computer (mac or pc) to your Apple TV. Even flash videos. I have not tested this yet, but if it works that would enable you to watch pretty much any streaming TV show posted on the web on your apple tv!
-There are other minor extra features you can add by jailbreaking: install a weather app (yawn), or use bluetooth keyboards with the ATV ("BTstack", installed from NitoTV). But I don't use any of those.
PS3 is great, I'm sure. . . but it's also several hundred $. I don't have an interest in a video game console. But an apple tv for $100 (or $85 if you buy it refurbished from apple.com)? Good deal.
