"I need some help here to convert some files with .avi extension to DVD compatible format such as VOB. To be honest, I tried some online freeware but they more or less lost some quality compared with my original AVI files. Is there any trust-worthy program to avoid quality loss after conversion?"

Talking about this, I do have a very good suggestion for you to convert AVI to VOB for burning DVD in the end. To better and more comprehensively explain the issue, I write this post in details for you and other users who come across the same problem.

Part 1. Why convert AVI to VOB

Audio Video Interleave, short for AVI, is a globally popular format originally developed by Microsoft as a file container file format. The data contained in the AVI files may be encoded in codecs, allowing the files to use less compression than other video file formats. VOB (Video Object), simply put, is a container format in DVD-Video media. Furthermore, VOB can contain video, audio, subtitle, menu and navigation contents multiplexed together into a stream form. Since AVI files cannot be directly burned to DVD, converting AVI to DVD compatible format VOB is more appropriate and recommended. To convert AVI to VOB, a reliable AVI to VOB converter is needed.
