VIDEO_Rm is a weird quirk from Philips and related recorders to store
recorder metadata.  Most modern payers, etc ignore it. However it could
create issues during "ripping" the video to hard drive for editing.

DVD-Video structure is explained here:
http://en.wikipedia.org/wiki/DVD-Video

You can get software that will "rip" the VOB files (the video) using
playback information in the IFO files (BUP are backuop IFO files). Once
you have that, you can edit the video stream and remaster the DVD.
Remastering will create new IFO files that your payer will use for
playback.  In summary:

1. rip (dvd::rip, or similar)
2. edit (Avidemux, kdenlive, openshot or similar)
3. master DVD iso (Q DVDauthor, bombono-dvd, Devede, DVDStyler, or simiar

Some of the editors can create DVD compliant files the you can burn to
DVD with K3B or similar program.

Have fun !
