Well, the Playstation 3 setting was promising... all my videos did show up with the "X" next to them on the HR20. However, none of them could play the audio stream of the video (the HR20 gave a message that the audio was unsupported, but did I want to play the video with out the sound). Even the mpeg-2 vids that I have that worked without the PS3 setting gave that audio error, so I imagine that both PS3 and HR20 use mpeg-2 but different audio stream support.
Thanks for your efforts, I know that it will get worked out eventually... now if Directv would support FF/RWD on their MediaShare video content, it would be worthwhile (that's their issue, though... doesn't matter what media server is used).

Incidentally, that other issue that I was having with the Directv screensaver kicking in after 5 mins. of an image slideshow has been resolved. I found info elsewhere that stated that if you hit the "Dash" button of the remote three times after the screensaver has kicked in, that will disable it. What wasn't mentioned that I figured out on my own was that once you do the Dash-Dash-Dash trick, you need to reboot the Directv box.
Also, not sure if anyone may have seen another, unrelated development request/question over here...
