Wrong? I never said they
needed to retain all the content (or even rip all of it) just that keeping a full mirror of the original disc is an advantage that's possible without compression. Once you compress to a media file, you lose the menu linking and disc structure, so either dump all the extra stuff or go about creating multiple media files of all of it that play separately.
I was trying to offer just basic initial information on ripping the disc in the simplest form to assist the OP - if they're new to the process of ripping a disc describing additional steps before they've got the software to hand (& because similar discussions in detail have been deleted) would be premature.

It'll vary from disc to disc, of course. A TV series may have several episodes and reach close to 9GB. A movie will typically be less, but there are long movies and higher bitrates too. I have quite a few discs on which the main movie element exceeds 7GB. That's without touching on the subject of discs that have multiple episodes in a indexed VOB set rather than easily identified separate VOBs!

Mp4 is not a compression codec, it's a 'container' format. The most popular usage of which is to contain h264 codec video with AAC audio.
Quote:
“MP4 is a container format much like AVI or MKV and it can be used to “house” many different types of compression codecs, not just H.264. It is true though that MP4 is a very popular choice for the H.264 format.”

For people who want to create media files witn h264 video but better audio (mp4 typically only supports AAC or mp3 - stereo) mkv is the next most common choice, as it can retain multiple audio formats, including various multichannel ones.
I tend to use AVIdemux for both mkv and mp4 file creation with h264 video, others swear by Handbrake - but most current ripping/editing/encoding software offers h264 at this stage (Handbrake dropped XviD some time ago).

Absolutely there's no need to compress, although the image loss can be minimised - it depends on how small you want to make the file, and what other settings you tweak on the way, and it can depend to an extent on the playback device being used (it's not clear what in this instance) I only raised this option because the OP mentions his friends watching films this way! Covering all bases early!
