im ripping a dvd using dvd decripter. and im having problems with the nimo codec pack. i do all the proper steps and inport the video into virtual dub. when i use the xvid codex to encode it to. the audio works fine but no video. could it be nimo codex pack. i also used the xvid codec off irc. it worked fine before but i went to update my ogg codex and it stoped working. i just formated and im still having problems. any ideas
