Okay, so I've been playing around with the SVN source and made some of my own "personalizations" to MB. I really love this thing and also love that I can customize it.
I like the direction they've gone in the latest build but I don't really like the implementation of either the stock alternate detail scene or Throgmorton's customized ones. So, I've stuck with my own custom detail screen based off the original default but with full-color and full-page backdrop. Mine is nowhere near as fancy as Throg's but I kind of like the simplicity. To each his own.
I've moved stuff around a bit to leave more room for the backdrop and notice I've added the aspect ratio since that's an important attribute to me (being a CIH guy). I still want to play around with the look and position of the play button, though. It doesn't really look right with the cover art rotated. Also, to fit in with the direction they seem to be going, I made my detail screen an option in the config parameters.
In the thumbstrip view I've also gone to nearly full-color backdrop and moved stuff around to allow it to show through better. Also with aspect ratio.
Notice a couple of more things here too.
First, behind the scenes, I've made the posters sort by "SortTitle" instead of the actual title. I use MM to create my xml and it has a "SortTitle" field which is very handy. Note how "The Dark Knight" is sorting in the "B"s because its sort title is "Batman Begins II". That keeps the Batman movies together (even though I don't have the others ripped right now). Also I like to group all my music concert DVDs together so I give them a sort title that starts with "Music - " and then they all group together.
Second, I've put BluRay and HDDVD frames on pertinent titles. I know this got pretty bad feedback from the MB crowd but I like them because I can pick them out quickly in the array of posters. Plus, as you might have noticed in the config shot, I can turn it off if I wish in the future. It will determine if a title is BD or HDDVD from the metadata if its there (again MM puts this in there) or, if not, it will look at the folder structure and try and determine it.
Last, notice the hotkeys at the bottom. I've made it so that hitting 1, 2, or 3 on the remote will take you directly to one of three genres. This is configurable as well.
Now that I've got the hang of it, I'm playing around with some other stuff like displaying graphic representations of aspect ratio.
This is fun stuff
Edit - I forgot I also implemented a translation for MPAARating. I don't have that tag in my xml because I used MM to create it and it creates a ParentalControl level instead. If there is no MPAARating tag, I read in this parental control tag (if it exists) and translate it to the MPAA Rating.
