H.265 (Encoding Format)
Please consider including H.265 encoding for your titles. My "Trucker's Woman (MED)" for instance, lost over a gig of storage space. I know storage is cheap, but these are seemingly identical quality and tiny! (RF 24 for the codec setting, if you want to know.)

I haven't tried any H.265 encoding but I re-encode everything I buy using XMedia Recode (free but not open source) and am able to reduce the file size by about 50% with nearly as good video quality. Heck, with the 1080p videos I can reduce the files from around 12GB to 2GB by re-encoding the video in h.264 with at the same full HD resolution and comparable quality (Constant Quality = 25 is the sweet spot to me). I don't really mind doing it myself but I know that most people don't want to spend the time figuring it out and doing it. Then again, maybe everyone streams the movies anymore, I don't know.
