Anybody experience the very very beginning of songs chopped (100ms) when burning a multiple song CD. I tried with the Sonar burner and my FreeStudio burner with same results. The multitrack is fine. One 2-trk-song, alone, burned to CD is also fine. Any ideas? thanks!

This can happen if the burning software hasn't been instructed to make a Red Book CD. Make sure you're specifying the required 2 seconds of silence at the front of the image.

Oh  OK. Are there typically such choices in CD burner software? I guess I figured the burners (especially in Sonar) were already configured as such. thanks.

SONAR does not create a fully Red Book-compliant CD on its own, as it has no internal burner but rather uses Windows' limited built-in CD burning feature. Most importantly, the CDs SONAR/Windows creates cannot be sent out as-is for duplication, and may even be incompatible with some CD players. It's really just there for making one-off quick reference burns, not final masters.
 
Most of us use dedicated CD-burning software for making CDs, with Nero and CD Architect being probably the most widely-used. There's a good chance your computer came bundled with some kind of CD-burning application, and in all likelihood it can make a Red Book CD.
 
 

The Windows burner is more for data than music. 
I use Nero 7 for burning and there are many other proper software programs too. Some are free. 
Try googling the "top 10 free CD burning apps". I find a lot of great software that way. 

are your Sonar Projects starting on the very first Bar ? 1:01 ?
if this is the case, as a test, try and drag the content to the second bar 2:01.

This was my guess as well

We make many Master-CDs for our customer:
There MUST be 250 to 400 ms silence in EACH wavefile before each song starts (Exceptionlive concerts).
Export your song(s) to wav-files - then import this wavefile(s) on an empty project.
Don't cut at the very beginning of each song. Just cut a half second before.
So theres is a half second silence before the first song starts.
Then export to new wav-files.
Burn your Audio-CDs with NERO. Then there are no problems.
The most CD-player need 100 - 250 ms to start and kill the first 0 - 200 ms.

Great info.  I did not know that about sonar/windows burner; I will try another. I believe I have CD architect. If that doesn't work I'll slide content up. 
 
Thanks!

Although the Redbook issue may be in play. I suspect Chuckebaby has the correct diagnosis because  many of my Sonar Projects begin at the very first measure.
 
What is the most effective way to move  song's content (many songs with 24-30 tracks with audio, midi, and automation)? 
 
Oh...and (just occurred to me)...What if?: Will Sonar export from multi to 2-track without error given a bar-1 starting point? If so, I could transfer the 2 tracks to something like Soundforge wherein you see the files and make sure there is sufficient space between tracks?
