LT/RT is a Dolby "Pro Logic" compatible surround stereo downmix. LO/RO is a "normal" 5.1ch -> 2ch downmix, optimized for stereophonic listening (with no embedded / specially encoded "surround" channels in the signal.) See
Dolby Metadata Guide, p. 13-14 for more information.
These settings govern how 5.1 channel surround soundtracks are handled in case you don't have a multi-channel home theater setup or if you're using an older, "Pro Logic" type surround decoder which gets its surround channel information piggybacked on ordinary 2-channel analog stereo signals. But I'm pretty sure
Metsolat was originally produced in ordinary 2-channel stereo and so those DVDs aren't too likely to include a 5.1 soundtrack at all...

The above-mentioned PDF from Dolby Labs includes some information about the "RF mode" on p. 10.

My own experiences recording from Kurzweil keyboards is that there must be something like "sound density" that is distinct from volume and can overload a channel even when subjective volume does not seem excessive.
That's one way to put it. Peak amplitude level on the VU meters doesn't tell you much about the (perceived) loudness of the recording... in order to determine that, you need to do some clever
RMS (root mean square) analysis on the signal. (Here's
a simplified introduction to the topic.) Anyway, you could easily record/produce signals which do not sound "loud" at all at normal listening volume but whose peak levels still overshoot the VU meters and sound distorted...
Pop/rock producers and radio stations like to compress all the dynamics out of their signal, so as to make things sound LOUD... and then there are modern producers (see
this rant about Nelly Furtado's
Say It Right which was produced by Timbaland) who deliberately use harsh digital overload distortion as an effect - it's rather irritating, really, especially on that particular song.
