Suggested format for movies with S790

I have an S790 player and I recently got a Blu-Ray drive for my PC. I have some Blu-Ray movies (and a bunch of older DVD movies) to serve. The DVDs are already copied to MPEG-2 inside a .mpg (I didn't want any conversion losses). With the Blu-ray and the large size of the MPEG-2 files, what would you suggest for a different format?

I use MakeMKV for all my DVD and Blu-Ray rips. It simply copies whatever video codec is used for the disc, and then whatever audio tracks you select. There is no loss of resolution and the video streams at its native rate. That means for a BD rip, you might see bitrates at or over 50 Mbps, which is why I have a gigabit wired network . Basically, MakeMKV just removes the encryption and copies the movie into a MKV container.

You can also copy the subtitle tracks, but Serviio does not yet support the format of captions contained on Blu-Ray discs. For DVDs, my Sony players (S3100) plays the MKV without transcoding, which allows me to select alternate audio and/or caption tracks. The MKV container works great, and is one of the only options for multiple audio and caption tracks.

Just make sure you have a lot of hard drive space. Ripped Blu-Ray movies can get quite large! 25 gig or more.

Thanks for the help.
