I joined some AVIs with Easy Video Joiner V5.21. The joined video plays fine but without any sound. If it makes any difference, the files were originally FLVs that I converted to AVIs with Replay Converter, because Easy Video Joiner doesn't handle FLVs. The sound IS there in the AVIs, so the error starts at Easy Video Joiner. The goal is to get them (either the FLVs or the AVIs) all as one joined piece onto a DVD with the sound. Thanks for the help.
