1) If you are serious about streaming / DLNA related activites, I highly recommend that you get a physical wired connection to your router/switch and that your router has a direct wired connection to the system that will be serving the content.
2) Wi-Fi will only be good enough to do Youtube and videos where you will downscale the content severly. You won't be able to use Wi-Fi for more serious HD video watching.
3) The Netgear
WNCE2001 is a very simple Universal Wireless Adapter that will work with any device that has a simple Ethernet port. It features Wireless-N technology that will definitely be faster than traditional b/g networks and should be faster compared to any Wi-Fi dongle that Panasonic will sell you (for an outrageous price, mind you).
DLNA is actually very powerful if you know how to use it.
What can you do with DLNA?
First off you can access all the video, audio and photo content right off your computer.
What is the benefit of using DLNA?
You don't really have to make multiple copies of your data (movies, photos, music). Normally people have the same content replicated on multiple drives. You don't have to do that anymore. You can have all your media present on your computer and access it from any device that is DLNA compliant.
How do I access the content on my computer through my DLNA compliant TV?
1) Simple, first you need a DLNA server. A great DLNA server that I personally use and recommend is the
PS3 Media Server. Install it on your computer using the link provided.
2) During initial run / setup, you might be prompted to allow PS3 Media Server access through your firewall. If so, allow it access.
3) Once you have installed it, use the options / settings menu and select which ever drives you would like your TV to access.
4) Configure your TV with the correct network information (IP Address, Subnet Mask, Gateway and DNS (optional))
5) You are done! Now just goto the "Media Server" source on your TV and you should be able to see "PS3 Media Server" in the list.
6) Select it and browse through your content and play any file that you like.
For complete compatibility with all files you might have to install additional codecs. I recommend installing any of the Codec Packs from
here. My personal favorite is the K-Lite Codec Pack.
NOTE
Keep in mind that the VT20 (and probably the V20) does not give you access to Zoom / other Aspect Ratio Settings while using the "Media Server Source". Just in case you happen to watch a cinemascope movie (Aspect Ration 2.35:1) you will not be able to zoom out the black bars.
