There are a couple of methods on how to fix this issue...
> 1) Manually take your Hard Drive out of your system and reformat it.
> 2) Possibly pay about $150.00[USD] to Sony for repairs. (1-800-345-SONY)
> 3) Buy a new Hard Drive.
or
> 4) If you can get to the XMB, wait for the next update to be released.

If you have outdated SKU like 20, 60 or 80, you can't get a warranty
for them. Instead they could possibly give you the 40GB and perhaps a
$100.00 to $200.00[USD] gift card.

My Advice to you is to Contact Sony Tech Support at 1-800-345-SONY (7669) and see what they can do about it.

Nat Type 3 to Nat Type 2:

..........Click Here .....................Click Here .....................Click Here

  If it dosent work try opening these ports:
* TCP Ports: 80, 443, 5223, and 10070 - 10080
* UDP Ports: 3478, 3479, 3658, 10070, and 50100

Also, I Just want to clear something up. I hear that people are thinking that NAT 1 is better than NAT 2. Infact NAT 1, 2 and 3 are all the same..
NAT1: Direct Connection withought a router
NAT2: Direct Connection when going through the router
NAT3: Indirect or Unstable Connection when going through the router

Nat 1 and 2 have no preformance difference, when Nat type 3 will disable some features. I just wanted to clear that up.

Tversity (http://download.tversity.com/TVersitySetup_1_0_0_3_RC2.exe)

- Check the “Windows Firewall should...”  box.
- Media Sharing. This is up to you. If you want to stream everything, check all of the boxes, if not, check w/e you want to use tversity for.
I use mine for everything so I set the settings below:


*NOTE* For people with Windows Vista, Check the "Disable Windows SSDP Discovery service" box. If you want to know why, click the "[Learn more online]" text.

4. After the setup completes. The TVersity Codec Pack 1.2 setup will start.
Check all of the boxes like below and click next.

Select the 2 options like below and click Finish

11. Now you should see this window:

12. Click on the top left button that looks like a Box, and a menu will show up.  (see picture below)

13. Click “Start Sharing”

15. Click Ok.

16. You’re done with the installation. Leave this window open.


II. TVersity Configuration

1. Click Settings on the top right.

The only thing I changed in the Settings is the Automatically start sharing the media when the computer starts.

In the Transcoder settings, play around with the Video Resolution. Mine is on the default 400x300 which works good on my SDTV. I don’t know how this will look on a HDTV because I don’t have one to test on. The testing will be up to you.  Some people suggest 1920x1080. Check it out.

2. After you’re done, Click Save on the bottom of the window.
