The Logitech Media Player included with the Logitech review is problematic - occasionally pausing causes it to stop or jump from video playback to music, etc. I am not seeing any alternative DLNA players in the Android Market that run under Google-TV. Are there any others out there that I am missing? Running Honeycomb 3.1.0.
The aVia Media Player is compatible with Google TV and is available in the Android Market on Google TV. https://market.android.com/details?id=com.videon.android.mediaplayer
I use Plex, and have had good results with it (also available in the Android Market) Plex seems to play a lot more of my video files than the stock Logitech app.
