I started with version 9 and it was not supposed to work with HD 1080p60 or AVCHD video. I found some "workarounds" and got by. Memory suggests that it was not until version 11 that AVCHD 2 was officially supported that included 1080p60. AVDHD 1 only included 1080i, not 1080p.
Again from memory, I think my favorite project setting in version 9 and 10 was listed under DSLR and was for 1920x1080p30. At output there was an "advanced" choice to make a preset for p60.
Premier Elements is now on version 15 and it would be rare if you had any trouble with 1080p on either a Mac or PC.
Version 10 is a pretty old program, pigglet. The world of video technology has come a long way since 2011. If you're going to work in hi-def and progressive frame video you really ought to consider a more recent version of the program.
It's actually kind of unfair to use a 5 year old version of a program and then complain that it's not state of the art.
I have been using PE 10 with Win 7 for many years and have had no problems creating HD BluRay or AVCHD discs.
I have no problem playing discs (either format) on PCs (Win 7 & XP) or on numerous BluRay/TV players
What has not been asked yet is what is the source of your video and is the source video indeed HD. I am currently using an Sony HD camcorder (HDRCX440) which records to a microSD card.
The project/capture settings I use are
Output settings for BluRay
Output settings for AVCHD
