You workflow is fine. It’s best to use an ac3 (Dolby) audio file instead of an aiff as it’s 1mbps less overhead (and a smaller file) for the DVD player. But, don’t use the ac3 preset without changing two parameters in the Inspector > Encoder > Audio tab: dialog normalization from -27 to -31 and data rate to 192 (it may already be 192, but check); and in the Preprocessing tab make sure Compression Preset is set to None. I’m pretty sure there’s a good tutorial about this on Ken Stone’s site. It’s also covered in Compressor’s user manual.
