Mount PC folder on my android, then serve audio/video through my Android to my TV via USB? My plan would be to allow me to connect my Android to my TV by USB, and then be able to play videos/audio from my Computer that is mounted over wifi on my Android. Is this currently possible, or is there a better way that I can accomplish this task (using only a USB cable/wifi and not having to copy files to my Android)

Thanks for any advice :D
There are definitely Android DLNA clients and servers which will allow you to share or receive videos or other media over a wireless network, see these previous questions:

DLNA enabled media player?
What can I do with DLNA on an android smartphone?
Can I get DLNA on my Droid?
What is the Android Answer to Air Video Server?

If you have a TV with a USB port, you should definitely be able to mount your phone's SD card as a drive and play the files on it (assuming they're encoded with codecs that your TV understands).

Also if you have a phone with video or HDMI out functionality you can play videos direct to the TV over a video or HDMI cable.

But, I don't think you'll be able to do things quite the way you describe. I don't know of any TVs that will mount a USB device as anything other than a mass storage device (USB drive) or a network adapter (normally only specific manufacturer approved adaptors), and it sounds like you want to stream movies via your phone rather than just play them from its storage. One problem you're going to face is that on an unmodified Android phone the moment you mount your phone as mass storage to one device (eg your TV) it's no longer accessible to other apps on your phone (such as whatever's receiving it from your PC).

TL;DR three realistic options:


Plug phone into PC copy movies onto SD card, unplug phone, plug into TV play as files
If your phone has TV-out, video-out or HDMI-out, plug your phone into the TV that way instead of USB and then either play from its storage, or from a streaming video client
If your TV is network connectible, use a DLNA client on your phone (see above question links) to push the movie from a DLNA server on the PC (eg Windows Media Player on Win 7, or Twonky server) to a DLNA compatible, network attached TV (or media streamer box attached to TV).
