   I can't help much with any fancy editing and fancy menus, but   
   video capture from hardware MPEG2 encoders is pretty close to   
   trivial.  I'm doing my old VHS tapes using a Hauppage USB device   
   with composite input.  To record, I just set up the device with   
   the right input and params, then cat from /dev/video{0,1,...} to   
   some-file.mpg, then control-C the cat process to terminate the   
   recording.   
      
   For splitting a long file into shorter files, I run mpeg2desc to   
   create a text file with descriptions of the MPEG file.  Then, I   
   wrote a C program to find "system header" lines, check the   
   timestamp of the immediately preceding "mpeg2 pack hdr" line, and   
   extract the low 32-bits of the offset into the MPEG file (keeping   
   track of roll-over to get any upper bits for >4GB files).  With   
   that, it's not hard to extract a piece of a MPEG file for a give   
   pair of time offsets.  Someone who knows awk could probably do it   
   in a few lines of awk, head -c, tail -c, etc.
