The only way to get a surround mix to play from a CD is to save the 5.1 channel files (@ 44.1 kHz) and then buy Minnetonka's Surcode DTS-CD encoder to make the CD-compatible files. This is a (comparitive) snip at $99 in the US, but has been removed from their rest-of-the-world online shop.
To make a DVD-A, save the channels (@48 kHz) and buy Minnetoka's diskWelder Bronze to do the job. (Or use WaveLab, which has DVD-A writing built in
)
DVD-V can also hold 48 kHz PCM files, but I don't know the easiest way to burn them easily as I've never had any interest in doing that. Lots of programs (e.g. Nero) can burn DVD-V with a Dolby-encoded soundtrack, which is probably easier, but you need to encode it first (try Minnetonka if all else fails!).
