VOB file merger for Linux

This can be done in a variety of ways. 1. cat file01.vob file02.vob >newfile.vob 2. mpgjoin file01.vob file02.vob -o newilfe.vob 3. mpgcat file01.vob file02.vob -o newilfe.vob 4. mpgtx -j file01.vob file02.vob -o newfile.vob You can also look into GOPChop and/or DVBCut, vobcopy -i /path/to/ripped/dvd/files/VIDEO_TS -n1 -l -o /path/to/put/files/file.vob ^^ -i = input path. The complete path -n = title number, if your not sure, use lsdvd or vobcopy -i /path/VIDEO_TS -I -l enables large file support. -o is the path to output the files. You can also use vobcopy to rip from the DVD driver.

dS as FRW

deSitter spacetime in the representation as a spatially flat Robertson-Walker universe, its metric is See eqn. 3.24 of Ford : arXiv:gr-qc/9707062v1 These coordinates cover one-half of the full deSitter space, but this is not a serious problem for our purposes. But in the context of inflationary models, one is interested in spacetimes which involve only a piece of deSitter space. See for example Kima, Oh and Park ( arXiv:hep-th/0212326v1 ) for discussion on relation between dS and FRW.
