At the moment, I see nothing in the “Legacy” section or on the Gen1 Support page(s) that links to the WDTV HD section of the community.
Even the Gen2 “Visit the WDTV HD Online Community” button takes you to http://www.wdtvlive.com/ which is the Community portal for the WDTV Live and Live Plus, not the WDTV HD.
Perhaps if the button actually led to the WDTV HD section and not the WDTV Live section (and if there were also buttons for the Gen1 pages), there wouldn’t be quite as many WDTV HD posts in the WDTV Live section. Even I originally made this mistake and posted in the wrong area, because it was not clear that that wasn’t the section for WDTV HD.
It would also help with solutions, since very few people will find WDTV HD solutions in the WDTV Live section even if they do search around before posting.
How hard can adding a couple of correct hyperlinks be?
