As far as I'm aware you need to select the 3D mode each time. However, the cinema mode seems to remember the 3D setting between runs.

Thanks for replying, by I don't have any problems with the setting remembering or not. It does remember the setting.

However, it doesnt really make any sense for having to even touch this setting. The player "should" already know if the movie is a 3D movie or not. At least, Arcsoft TMT 5 doesnt require someone to point out that the movie is 3D or not. It already knows; and, fully automatic.

Ideally, that button should only be used if you have to force PowerDVD to use 3D mode when it can't detect them on their own; not for the user to do it every single time.

This has been reported a long time ago, see http://forum.cyberlink.com/forum/posts/list/21658.page

I hope it will be in the upcoming patch, but as it seems it's only a handful of us who seem to care about the problem, I'm not too hopeful.

At first I too missed the auto 3d switching feature from TMT and would have liked to have it, but have since also found it useful to have it manual. I find it useful if for some reason i want to not watch in 3d I can and some other testing purposes etc.

I find this feature would be useful if you could toggle it always on or off as needed.
