In the meanwhile I tried a couple of things, and using the pipe on
Linux actually works very nicely, it's even faster than simple tar for
some reasons..

[andrea@andreacrotti isos]$ time tar czpvf - file1.avi file2.avi |
split -d -b 1000M - inchunks

[andrea@andreacrotti isos]$ time tar czpvf total.tar.gz file1.avi file2.avi
