Subject: Renamed compress_vob_file method to encode_vob_file and moved to top of function... 
X-Git-Tag: 1_0~15
X-Git-Url: http://git.pippins.net/embedvideo/.git/static/%7Blink_hometeaching%7D?a=commitdiff_plain;h=aacf74d70ad8d74b29fdffc4d5d9a98ae3485c11;p=rip_dvd%2F.git

Renamed compress_vob_file method to encode_vob_file and moved to top of function list.
Since this will probably be the most commonly changed section of code, moved it up!
