If your desire is to convert the AVI files to a DVD-related file structure for the purpose of playback on a conventional DVD standalone player, do the following:\n\n1. Convert the AVI/mpeg file(s) to a DVD compliant mpeg-2 file(s) using "TMPGEnc" or "TMPGEnc Plus". Use the DVD template (NTSC or PAL) form the "Project Wizard" to help you accomplish the task.\n\n2. Then use "TMPGEnc DVD Author" (different than "TMPGEnc") to author the newly created mpeg-2 into a DVD-related file structure (.IFO, .BUP, .VOB). As an alternative, you can use "DVDLab" to author as well.\n\n3. If the combined filesize of the project exceeds 4.37 Gig, use "DVD Shrink" or similar transcoding program to compress.\n\n4. Use "Nero" or similar burning program to burn onto a DVD (r, rw) disk.

The iPod plays MPEG-4 files with either the basic MPEG-4 video codec or the more advanced H.264 codec. The standard way to do this is using QuickTime Pro which a serial you buy for QuickTime Player that enables import/export/file conversions between many formats. There you find a special Export to iPod setting which makes it just a few clicks away. However, all software that create files based on the international standard MPEG-4 will work for this conversions. There are many such programs available...here is one guide for what you are doing...\n\nhttp://forums.afterdawn.com/thread_view.cfm/253137

It is not possible to do this without changing the quality. Neither AVI or MPEG2 (what DVDs use) are lossless formats. They are lossy, meaning that some quality is lost in encoding. Even reencoding from one format back to itself will lose quality.\n\nSo, it cannot be done.\nBut you can convert from one format to another (you will just lose quality). Make sure, however, that you can legally do so. Unauthorized copying of a DVD is a federal crime punishable by up to 10 years in prison and/or a $100,000 fine, according to the FBI warning at the beginning of the DVD you're about to pirate ;-)
