[Mplayer-advusers] mending vob files

Hi guys, I have four vob files, the first three of 1gb each, the last of about 500mb, of one movie, that I wish to make one long vob of. I tried cat *.vob | mencoder -oac copy -ovc copy -o movie.vob - but got this error about a 20 seconds or so into the copy: Too many audio packets in the buffer: (4096 in 8241152 bytes). Maybe you are playing a non-interleaved stream/file or the codec failed? For AVI files, try to force non-interleaved mode with the -ni option. adding -ni didn't help If I just cat them together the image is fine, but sound is completely buggerd. What is the correct way of doing this? Thank you Kind regards Hans du Plooy hdp@webmail.co.za
