"...it puts the letterboxes up there they are not 100% black."

It's the TV. It needs to be calibrated with color bars.

Take care,

Thanks John from me too!
I loaded down the bitcalculator and put in a 110 min long mpeg for dvd. Recomended max VBR setting were 9 704 000.

John, your recomended VBR setting is max 8 000 000.
Is there a reason for setting max to 8 000 000 or can I go for
the bit calculators max setting.

The absolute maximum bitrate for a DVD is 9.8 Mbits/sec. This figure is the total for both the audio and video combined. All DVD players are supposed to be able to play discs authored at this maximum bitrate. However, for various reasons, there are a lot of them that can't, either the player isn't up to the task or the blank DVD media or the burn itself isn't of sufficiently high quality.

After a lot of reading and some experiments of my own over thousands of burned discs, I settled on a maximum of 8Mbits/sec for the video and usually 192Kbps or 256Kbps .AC3 audio. However, if I wanted to, I could use the 8Mbps video with uncompressed 48k audio and still just sneak in under the maximum allowable bitrate.

That said, yes, you can go for the maximum setting and see what happens, As long as the total of the audio and video don't exceed 9.8Mbits/sec, then it is considered within spec.

Thanks a lot
Some more maybe silly questions I´ve got.
The bit calc recomend max 9 704 000 Av 5 544 000 min 3 320 000 for 110 min video length.
If I change max to 8 000 000 to be in the sure side can I still use
the other settings (5 544 000 and 3 320 000) or must there be a certain relation between Max/Av/Min?

"Your template" Max 8 000 000 Av 6 590 000 Min 3 952 are for
NTSC widescreen can I use it for PAL too?

Quality can be set to good or best AND with a slider on videotab.
Why is it 2 ways to set quality and which one to choose - or both?

Is it overkill to set best quality when renderering VBR 2 pass?
Thanks again

"If I change max to 8 000 000 to be in the sure side can I still use the other settings"

Yes.

"...are for NTSC widescreen can I use it for PAL too?"

If you're talking about the bitrate calculator, the values are vaild of NTSC and PAL. If you're talking about the MPEG2 encoding template in Vegas, then you must start with the PAL Widescreen template and input the bitrate values into it. PAL and NTSC have different frame sizes and frame rates, so you must start with the correct template.

"Quality can be set to good or best AND with a slider on videotab."

The "better/best" setting is the quality at which Vegas renders the project and feeds it to the encoder. The slider sets the quality of the encoder itself. If you want maximum quality (and who doesn't?) leave the render setting to "Best" and the quality slider in the encoder at maximum.

There is way too much good info here I am reading and learning. I downloaded the bit rate calculator and trying to figure that one out
