Hello, after finally purchasing a dvd-burner, I am just starting to make backups of my precious dvd-collection. But now I ran into a problem with the widely used combination of tccat, tcextract and mplex which I can not resolve on my own, so any help would be greatly appreciated :)
After some testing I found, that mplex is having problems with a chapter break. While the following gives perfect results # tccat -i dvdbackup -T1,14,2 | tcextract -t vob -x mpeg2 > c14.m2v # tccat -i dvdbackup -T1,14 | tcextract -t vob -x ac3 -a 1 > c14.ac3 # mplex -f 8 -o c14.vob c14.m2v c14.ac3 -S 0 # tccat -i dvdbackup -T1,15,2 | tcextract -t vob -x mpeg2 > c15.m2v # tccat -i dvdbackup -T1,15 | tcextract -t vob -x ac3 -a 1 > c15.ac3 # mplex -f 8 -o c15.vob c15.m2v c15.ac3 -S 0 I get this, when multiplexing both chapters: # tccat -i dvdbackup -T1,14-15,2 | tcextract -t vob -x mpeg2 > c14_15.m2v tc_memcpy: using mmxext for memcpy libdvdread: Using libdvdcss version 1.2.8 for DVD access libdvdread: Couldn't find device name. # tccat -i dvdbackup -T1,14-15 | tcextract -t vob -x ac3 -a 1 > c14_15.ac3 tc_memcpy: using mmxext for memcpy libdvdread: Using libdvdcss version 1.2.8 for DVD access libdvdread: Couldn't find device name. # mplex -f 8 -o c14_15.vob c14_15.m2v c14_15.ac3 -S 0 INFO: [mplex] mplex version 1.6.2 (2.2.3 $Date: 2004/01/13 20:45:26 $) INFO: [mplex] File c14_15.m2v looks like an MPEG Video stream.
