i have been ripping and compressing dvds for a while now with mencoder. only recently has mencoder been producing compressed dvd-rips with a bad, or missing index. heres what i do for a typical dvd-rip and compression:

mencoder -dvd 1 -alang en -oac copy -ovc copy -o /movies/riptemps/file.avi

mencoder file.avi -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=1200:vhq:vpass=1 -oac mp3lame -lameopts abr:br=96 -vop scale=640:272,crop=710:276:6:100 -o file-compressed.avi && mencoder file.avi -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=1200:vhq:vpass=2 -oac mp3lame -lameopts abr:br=96 -vop scale=640:272,crop=710:276:6:100 -o file-compressed.avi                                                                                

this usually resulted in a good dvd-rip, it had an index etc...

but now when i do this (using the same commands above) now, it seem that most of the time, i get a AVI with no index, or a bad one. gmplayer has to rebuild the index to allow me to be able to seek, and even then when i am able to seek, it looks weird. im not too sure how to describe this... it looks like when i seek it skipped a keyframe, so when the codec moes parts of the picture when playing the movie, it moes the wrong parts, so things look bad, and have the wrong colors---until the next keyframe fixes it. and of couse after the next keyframe, if i seek again, it goes threw the whole process again.

so i thought maybe running the file-compressed.avi file thew mencoder again would fix this, having it rebuild the index, with the folling command:

mencoder -idx file-compressed.avi -ovc copy -oac copy -o file.avi

but it still has no index or a bad index!! ugh...

i origionally compressed the movie with a cvs version of mplayer... 3/13/2003 i think. but i tried the reindexing with mencoder using mplayer 0.90rc5.

any ideas as to how to fix this??
