I just bought it. Are you saying they won’t support Blu-Ray?
Although you just bought it, it is a two year old product today. Anyway, menus for DVDs and Blu-ray discs are entirely different: Blu-ray disc menus are Java-based, and WDTV is not Java-enabled. If you look around these forums, you will find people who rip BD discs and play them on WDTV, by transcoding the BD ISO file to mkv file and they play fine, I am one of those people. I can move through mkv chapters, but without menu feature. I have converted many files this way and they work fine.
Arnie, you are new here and have posted quite a few messages since you joined this forum, yet in the great majority of them you slam the WDTV for this or that. Request that you spend more effort learning about the WDTV and less effort slamming it every chance you get. Good grief, relax! You are quickly becoming high maintenance.
