Roxio Creator NXT Pro 24b/96k?

[clashradio]

I have The Doors Perception 5.1 DVD-A of The Soft Parade album that I ripped and made my own custom two-track mix. I ripped it at 24/96, and want to put it back on an audio dvd at 24/96, or maybe it's called DVD-V? I thought I could use Roxio like I have for other audio-only dvd's. In the past I must have used 16/48 because I've never had a problem. I get a message that says "this file is not supported" I'm guessing it's because the file is above 16b and/or 48k? I did select the "create dvd music discs" option.

Does anyone know what the quantization limits are for Roxio NXT Pro? I tried to find it, but got nowhere.

I don't need any menus, video, or pictures. I burned a cd at 16/44, but also want to see how it sounds at the full rez.

I do have Sony Vegas Pro 12, but the highest sample rate output it shows is 48k. I thought about just making the dvd that way.

I tried downloading Lplex, but didn't have much luck unzipping everything.

Is there a newer, better version of Roxio? I admit I'm a little slow when it comes to using new programs.
