I have some .mpg files I've created from downloading .tivo files to my Linux box and decrypting them. I would like to manually (as opposed to having some server do it) transcode them to Xvid. I'm pretty new to the transcoding world so I would like to know what tools people recommend (I'm fine with using command-line tools if they are the best) and any pointers to specific guides/tutorials on using them to transcode to Xvid. If it turns out there's nothing good for Linux I'm willing to use something under Windows, but I prefer Linux since my Linux box has a significantly more powerful CPU than my Windows box. Thanks!
