There are many products on the market today that are capable of converting rmvb files to DVD files. Unfortunately, however, not all of these products are created equally, and buyers will have to do their research to find one that provides quick, high quality service.
One product to consider is the CucoSoft Mpeg/Mov/RMVB/DivX/Avi to DVD/VCD/SVCD Covertor. This easy to use device can successfully covert any video file to the VCD, DVD, SVCD, MPEG1, or MPEG2 format. This converter can be purchased in a "lite" version or a "pro" version. The lite version just provides the basic conversion process, while the pro version also has DVD Author Express and a DVD/VCD/SVCD Burner Engine. It is only optimized for a 64 bit CPU and converts videos much more quickly than the lite version. Typically, the product sells for around $30 for the pro version.
