Have a look at the "Playback Info" tag for the files. It stores all sorts of settings for playback of individual files, including the Aspect Ratio and Zoom, Stream, Subtitles, etc. If you make the changes you want on one file, then you may be able to copy those settings to all the files you want to change. Backup your database before applying the changes to lots of files!
It isn't a default for newly ripped files, but if all you want to do is make those settings for files you have previously ripped, and future files will be ripped differently, then this may be the solution. I haven't got appropriate files to test. Make sure you look at the "Playback Info" tag on the first file you set up, and understand what the settings are. There are mostly obvious, although a little cryptic regarding the specifics.
