Boxee, one of the many contenders for the media center crown, has just released a new app that lets you stream music, video, and photos from your social networks like Facebook and Twitter, and from your Windows or Mac PC, straight to your iPad.

It also lets you “watch later”, which sounds like Instapaper for videos, and will send content via AirPlay to your Apple TV. Looks like Boxee aims to be your one stop content app.

Details and screenshots after the break!

Boxee for iPad brings videos from Facebook, Twitter, Tumblr, and your computer all onto your ipad so you can find and watch new videos or favorites on the train, in bed, on the couch, on the john, during boring conversation, on the patio, from the roof deck, in an abandoned bunker, on the side of a mountain….

SOCIAL: Never miss a hilarious or inspiring new video from your friends again. Boxee connects to your social life and delivers every video your friends share on Facebook, Twitter, Buzz, and Tumblr to your iPad. Return the favor and share favorites with two taps. Boxee brings video sharing to the iPad in a way that’s simple and unique.

WATCH LATER: Each day, we’re bombarded by video from everywhere. Collect them in one place and save them for later with Boxee. Queue YouTube videos, TED talks, and, well, whatever you want to watch on your iPad, whenever you want. Your commute just got its own video playlist.

MEDIA STREAMING: Stop wasting hours converting and syncing videos to your iPad. Boxee streams videos, music, and photos from your PC/Mac to your iPad over WiFi. You pick the video, we handle the rest — no cables or wires necessary.

SEND TO BOXEE BOX: Watching video on your iPad and want it on the big screen? Send videos straight to your TV via a Boxee Box so everyone in your living room can enjoy. Now you can go back to playing Angry Birds on the iPad while you watch : )

Boxee will soon release its own iPad app which will offer streaming to other devices that can run the Boxee software. The Boxee app will not use AirPlay but something similar provided by Boxee itself.

VP of Marketing for Boxee, Andrew Kippen describes it as “kinda like AirPlay, but not quite”. The iPad app will allow you to stream content from your original iPad or iPad 2 to any device running the Boxee software. This would include the Boxee Box, PC’s, Mac’s and Linux machines.

If you don’t know, Boxee provides an easy way watch movies, TV shows and clips from the Internet as well as locally or networked stored content. There is no mention of what video file types the iPad app will support at this stage, but we imagine it will be quite extensive and not limited to m4v or mp4. We will keep you informed as we get more information.

We heart XBMC, which debuted as a gorgeous and highly polished replacement OS on the original XBox, and has grown up to be the go-to media center for all types of gear now (and is the background technology behind Boxee to boot!). So what could be better than a killer open-source media center? A killer open-source media-center you can now access via your iPhone with XBMC Streamer [iTunes link], of course!

The XBMC Streamer connects to a running XBMC host and streams your music from your house, to you… anywhere in the world! You will never have to worry about running out of space on your Iphone again. Never again will you have to pick and choose which albums to take with you and which albums to leave at home. The XBMC Streamer gives you access to every song, artist, and album in your XBMC library.

And what’s even better than all this? The awesome folks at Collect3 have given TiPb three (3) promo codes to give to you! Just head on over to our forums and tell us the most embarrassing song in your media collection. That’s right! We want the best of your worst!

Boxee, a branch of XBMC (originally Xbox Media Center, something that gave my original Xbox a life and power well beyond what Microsoft ever intended) is free alternative to Microsoft’s Media Center and Apple’s Front Row and AppleTV that many believe soundly beats both on features alone. It’s had some hiccups as of late, what with Big Media pulling Hulu content (they likely don’t want Hulu on TVs as the same shows fetch much higher ad revenue from traditional networks than they do from the internet streams), but that hasn’t stopped them from pushing forward. The latest example? Boxee Remote for iPhone:

• the boxee remote app has two modes: Gesture and Buttons
• in the Gesture mode you need to hold down your thumb and move it around in order to navigate.
• clicking on the boxee logo acts as Select/Play/Pause
• dragging the boxee logo to the edges of the screen will act as a continuous up/down/left/right
• clicking in an input field will open up the iPhone Qwerty keyboard and will enable you to easily enter text
• the app works over WiFi, so make sure the WiFi on your iPhone is turned on

If you’re a Boxee user and you try this out, let us know how it works for you!
