I know it's possible on the software side..but what about hardware?? It's got TV OUT? BUT NO TV IN? hmm

Wouldn't that require an encoder and tuner built into the device? Neither of which are there as far as we know.

Perhaps with a usb tv tuner once Host mode becomes available. Until that happens, hardwarewise I would say a big no. Unless you get somethng that can broadcast your tv over your internet like a sling box.

one thing id like to know is if it were technically possible to record internet streams? ofc via some 3rd party app

I know it's possible on the software side..but what about hardware?? It's got TV OUT? BUT NO TV IN? hmmYou can receive 'TV' via BlueTooth & DVB-H using Nokia Mobile TV Receiver SU-33W (http://talk.maemo.org/showthread.php?t=32062) however it is currently unknown whether this will work together with Nokia N900. Please see referred link for updated information on this compatibility.
You can also use IP via WiFi or 3G to watch 'TV'.
No TV in and no host mode (would minimally require kernel recompile)
Something like a HAVA or other video to network should work via wifi.
Or you could point the camera at the screen.

easter egg?
If so, it won't be ATSC anyway. *sigh*

Symbian S60 3rd had a free app called PiiPTV. It allowed you to place software on your cable connected Media Center PC and control and view it via your mobile. If they can stream to the device, I don't see why it can't store it. I think that app was open source, too, not sure.
What a coincidence - I was bout to create a similar thread! :-)
I have an idea for the Push N900 project that would require the N900 to display live video from an external source (like a surveillance camera or the video output of another N900).
Without USB host mode (grrrr...), I thought of some other options:
1) Use a wi-fi video encoder / video server
It might work if I can connect the N900 with it in ad-hoc mode. The benefits are easy setup (I hope), high bandwidth (and thus good video quality) and basically no need for cables on the N900 – a very nice setup! The major disadvantage is the bulk and high cost of the wireless video encoder.
2) Use a video-over-bluetooth solution
I searched for this but could not find any off-the-shelf product, so unless I find one, I’d have a lot of work to make this happen… and the video quality would not be very good (max. bit rate should be around 700kb/s, I guess).
3) Use N900 USB port connected to a UBS host and USB video capture device
I believe this could work, but I never did anything like this. It might be a complex, bulky and expensive solution, but OTOH, this could allow other interesting hacks.
What do you think? Is there any other way to display video on the N900 from an external source?

Bluetooth:

(or a jpeg to serial plus a bluetooth from sparkfun.com)
The USB might be able to use something like a beagleboard in OTG host mode to act as a network endpoint.
The hackiest way would be just to get a display of sufficient resolution and small size with proper opetics and mount the n900 so the camera is just watching the display - but displaying and recording.

However instead of using a Nokia N900 to record and broadcast I think its cheaper to use a Sheevaplug (http://hackaday.com/2009/04/29/hackit-sheevaplug/) (with USB and Gigabit ethernet), connect a USB (web)cam on it, and let this run your streaming server instead.
Or one of the other options provided above.
Your project might still be cool for e.g. PUSH Nokia!
Turn the n900 into a mimo usb monitor.
Might require some kernel hacking, but the port is there, should be fast enough, and you can "display". Recording would take a bit more.

this is neat software if you have a windows box with a tv tuner http://www.orb.com/en/how_it_works
There is also the micro SD card interface. Unless something is really strange, it is a standard SPI interface, though might have a few quirks. And there are things which can do video to SPI.
Thank you all for all your input! :-)
allnameswereout, I just submitted my project to the Push N900. ;-) I'm planning a Kite Aerial Photography (KAP) controller, and I want to send live video from an airborne N900 to another one on the ground. You can see a simple mock-up of the idea on this video on YouTube (http://www.youtube.com/watch?v=MV6QLVMjguA).

You'll need the optional VCR attachment.
IF it is possible to get the N900 USB port to function as a USB host controller you could use a device like a DVB-T USB receiver for watching (and recording) TV.
The smallest DVB-T receiver I know of is the new PCTV Picostick:
Picostick DVB-T (http://www.pctvsystems.com/Products/ProductsEuropeAsia/Digitalproducts/PCTVpicoStick/tabid/203/language/en-GB/Default.aspx)
I wonder if devices with micro-USB ports exist

I wonder if devices with micro-USB ports exist1) You still need an external power source (e.g. USB hub).
2) You also need an antenna if you want some kind of good signal.
3) The chipset of this USB stick is unknown; hence its unknown how (well) the Linux support is.
Still, seems like a nice device. Just the price is like 80 EUR. I've seen DVB-T USB sticks for 50 EUR.
