increase volume of audio on dvd files

[mufngruf]

Hello,
After decades of waiting and searching I have finally acquired copies of some favourite seventies tv shows on dvd (Video-ts).
Although delighted, i find the audio a little low on volume. Is there a non-geek way to rip the folder and increase the volume before re-recording to a fresh disk?
Thanks for any help.
tony

MPEG streamclip (http://www.squared5.com/) may be able to help you. You'll need the Apple MPEG 2 component (http://www.apple.com/quicktime/mpeg2/). Failing that, FFMPEG X (http://www.ffmpegx.com/) is worth a look.
