One of the most pleasant surprises for me with the 2.0 update is the Sony seems to have tweaked the audio stack in the GTV box. When the Sony nsz-gt1 first came out it could not output dolby digital sound on 5.1dd feeds coming in through the hdmi input. So if you were watching a movie with 5.1 sound on HBO through your cable box with the nsz-gt1 in the chain you would get 2.0 sound and not the full 5.1 This was a big deal to me when it first came out. Logitech decided on the opposite which was to nail up a 5.1 connection regardless of what the input was sending in. So you get 5.1 in the hbo movies example, but if you are watching netflix (almost always 2ch) then you are getting sound out of your left and right speakers only. Center are rears are lifeless. Sony ended up coming out with a "beta" patch to address this which for the most part worked- but in my specific case caused my Marantz processor to occasionbally drop digital sound especially when playing back recorded content on the DVR. I would have to pause for a second and then hit play again to get sound back. This was an inconvenience I learned to live with. With 2.0 I was able to go into the settings, turn off the "beta" pass-through setting but am still getting 5.1 sound on dolby digital sources and 2ch sound (which can be matrixed for 5.1 with prologic 2 or DTS NEO) on SD channels and netflix and no audio drop outs. If you had the beta pass-through enabled in 1.0- this setting will have been preserved in the 2.0 upgrade. I recommend trying to turn it off to see how you do. It is working perfectly for me.
