Is there any way to do this on a DVD-R?

I just got a burner, and it would be cool to have a vast collection of music always accessible. It might even be worth getting a cheap DVD player to dedicate to music!

I've heard it before, I'm not sure how to put MPEG-1 stuff on a DVD. I have Pinnacle Studio 8, NeoDVD and Nero (as well as the free TMPGEnc, of course). I don't see an option that would seem to make that possible...

Anyone else have success?

Hi BoxOfSnoo,

For DVD, encode an MPEG-1 video track CBR at 10Kbps (yes, TEN Kilobits per second, just to keep a very low stream instead of zero) at 352x240 (no video selected), and encode your audio at 224Kbps or higher at 48Khz. Or AC3 if you can
That will give you many MANY hours of music on a single DVD
Look here at the DVD specs, so you can get an idea of what you can do: http://www.dvddemystified.com/dvdfaq.html#3.4

Edit: Correction, encode MPEG-2 with 3:2 pulldown, because if you encode MPEG-1 you must encode 29.97fps and you'll loose space. So encode MPEG-2 at 23.976 with the 3:2 flag enabled.
Do the math, and figure how many hours of music you can get in a DVD with audio encoded at 384Kbps (use Joint-stereo, BTW)

I just did. It's about 24 hours

I don't think the framerate will matter when you're using CBR, it should be 10Kbps either way.

If my math is right, you can get almost 6 and a half hours of uncompressed audio on a single DVD with this method. And it will work in all DVD players. Too bad most sources are 44.1kHz and you have to convert to 48kHz first...

Or you could use the video for something other than a blank screen. Maybe a time display, or show a lyrics page (a scanner would be really useful, just grab the liner notes). A nifty idea I've wanted to try for a while (that may have been posted on this forum a while back) would be to capture visualization from Winamp somehow and put it on disc. But then you'd have to sacrifice a bit of audio space to store it (which shouldn't be much of a problem on DVD).

Yep. You're right, and I'm posting too fast

At 384Kbps, you get:

~384,000Kbps / 8 = ~48,000 bytes per second.
A DVD has a formatted capacity of ~4,300,000,000 bytes.
So 4,300,000,00 / 48,000 = 89,583.33 seconds or 24.848 hours of music

You're still posting too fast, I was commenting on how you could get over 6 hours of uncompressed, 1536kbps, LPCM audio on a DVD

Since MPEG audio is "optional" (at least here in NTSC-land if I'm reading the FAQ properly), I figured LPCM would be the best way to get it to work on all players and still get several hours on a disc (4-5 CDs worth, at least). But in reality, I've never seen a player that doesn't do MPEG audio, so I'd probably use it and get 24 hours like you said

I would go with 384Kbps audio, because frankly, at that bitrate there is no audible difference (to the human ear) compared to uncompressed audio
And 24 hours of music on a single DVD(+-)R is sweeeeeet
