You did everything in the right order it appears.
1. Connect HR20 to network
2. Run Network Test
3. Download CE
4. Enable VOD
5. Run network test again (so D* can see that your box is a CE qualified unit)
6. Sit back and relax, occasionally checking to see if Channel 1000 is activated and/or checking your D* account online to see if the For Engineering Only code is on your Recent Activity. You can see if VOD is correctly activated by going to My Playlist and if you see Queue on the left-hand menu, it is all set on your end. But D* does need to add that Engineering code before you can see anything.
What do mean by "Queue" in te my playlist menu? I do not see that in there. All I see is what is recorded on my DVR.
