Authoring DVD - 5.1 audio

[blueznl]

I'm not entirely sure where to post this, or even how to approach this, so bear with me.

In a nutshell, I want to create my own 5.1 test disc, primarily to test audio.

I'm able to create audio files in Audacity, export them as 5.1 AC3, and in itself that works. But how do I get those files onto a DVD, ready for playback? I've got them on regular CD using Nero, and also using BeSweet + BeSure, but no luck getting any onto a DVD yet.

I've been looking at a few authoring tools, and half of them crash, and the other half I can't seem to get to grips with (though I'm pretty sure it must be me )

Could anyone point me in the right direction? What software should I use? (Preferably free or very cheap, hey, I'm dutch after all )

Assuming it is a DVD compliant audio track, all you need is an accompanying video track and a decent authoring tool. GUIForDVDAuthor, DVD Styler are good places to start for free

I am getting the horrid suspicion the problem is creating a compliant audio track... How would one accomplish that?

Euh, better put, what are the requirements for a file that can be used? 48 khz 5.1 ac3 would work?

The official allowed formats for the audio tracks on a DVD Video are:

PCM: 48 kHz or 96 kHz sampling rate, 16 bit or 24 bit Linear PCM, 2 to 6 channels, up to 6144 kbit/s. N.B. 16-bit 48 kHz 8 channel PCM is allowed by the DVD-Video specification but is not well-supported by authoring applications or players.

AC-3: 48 kHz sampling rate, 1 to 5.1 (6) channels, up to 448 kbit/s

DTS: 48 kHz or 96 kHz sampling rate, 2 to 6.1 channels, Half Rate (768 kbit/s) or Full Rate (1536 kbit/s)

MP2: 48 kHz sampling rate, 1 to 7.1 channels, up to 912 kbit/s

Thanks, I'm slowly beginning to understand what's going on, have to retrace my steps...
