Another small update:

Every once in a while, the WD TV Live unit had trouble accessing the network share. Sometimes, it could see the list of movies, but the unit would reset itself when trying to play one. Other times, I would get a username/password prompt.

A bit of Googling later, the solution is as follows:

Windows7 has some issues broadcasting its availability on a network. The steps below should help solve these issues:


First, configure Sharing and Discovery

1. Navigate to the Network and Sharing Center via the Control Panel
   
2. Click on the Advanced Sharing Options link
   
3. Set the values as follows:
   
   • Network Discovery - ON
   • File Sharing - ON
   • Public Folder Sharing - OFF
   • Printer Sharing - ON
   • Password Protected Sharing - OFF
   • Media Sharing - OFF

Next, configure the folder you want to share

1. Select the folder
2. Right-click and choose 'Share' from the menu
3. From the drop-down box select the Everyone (All users in this list) account, making sure permissions are set to 'Read'
4. Click the buttons Add, Share and Done.
5. Do the above steps for any/all folders to share

Next, some further registry "tweaks"

WARNING: Editing the registry incorrectly can cause the system to become unstable and unusable. Follow the instructions below at your own risk - I am not responsible for any damage caused by following these steps.

1. Open the registry editor as an administrator
2. Navigate to: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Contro l\Lsa\
3. Double-click on "everyoneincludesanonymous" and change the "Value data" from "0" to "1"
4. Double-click on "NoLmHash" and change the "Value data" from "1" to "0"
5. Navigate to: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Servic es\LanManServer\Parameters\
6. Double-click on "restrictnullsessaccess" and change the "Value data" from "1" to "0"
7. Close the registry editor

Finally, restart your PC.

The first and second sections are simple enough and I had those right, but after the registry tweak, I haven't had any more trouble. While this was to fix network share access issues with the WD TV Live unit, it will probably work for other similar non-Windows devices.
