Help. Color correction?

Hi, I badly need help with my color correction problem. I calibrated my monitor and I'm happy with the image but when I watch it on DVD, the picture looks completely different. I realize there is a difference but not this much, on the tv the contrast is terrible, the blacks are too dark and the lights are blown out, whereas on the monitor the picture looks very mild, almost raw.
A bit of info: I'm rendering in PAL 25fps, all of my colors are legal in the video scopes, I'm rendering using cineform v3.2.2 then using TMPGeng4.0 xpress to convert from HD to SD.

So how can I get a picture on a standalone DVD that looks the same/similar to what I see on my monitor?

Thank you.
 
maybe u should try using the waveform monitor. then u can use the Levels filter to adjust the exposure/luminance of ya picture. ideally, black should be at 0% and whites at 100%.
of course u should use ya eyes in conjuction with the scopes. the Sony Levels plugin should be adequate. set the levels at 0% for blacks by using the INPUT START slider. keep the whites at 100% with the OUTPUT START slider. if u have superwhites u can keep them below 100% by using the OUTPUT END slider. if the blacks are below 0%, u can push them up with the INPUT END slider.
then use the GAMMA to adjust the subjective brightness. gamma above 1.0 brightens and vice versa.
N/B: use the levels plugin in the mode that affects all the video channels. as u do the levels adjustments u may notice a change in the chroma saturation. do the necessary adjustments thereof with the color corrector or HSL.
 
You need to preview on a production monitor or at least a TV screen. What you see on your computer monitor will in no way inform you as to what you're going to see on a TV screen once you go to DVD. A computer monitor and a TV are two completely different things.

Thanks David, I took your advice about hookig up an external TV and calibrating for television is now so much easier, the thing is the image doesn't look so great on a PC monitor and I'm a little worried about the prospect of what the film will look like to anyone who watches the film on their PC - do I just have to live with this and hope that not many people watch DVDs on their computers?

Well, you have to be sure you calibrate the external TV. Use color bars.

If it looks good on a properly-calibrated external screen (a production monitor is best), then it should look OK on a computer screen. Of course, you have no control over what other people do to their own screens, so just make sure you calibrate and it looks good on those screens.

Can i use the colour bars on that site, it says I should feed the colour bars into a tv through a camera rather than through the website.
'The graphics on this page are for example only. You’ll want to use real color bars generated from a camera and viewed on a VIDEO monitor or TV set.'

I have my tv plugged into my s-video port on my GPU.
 
Gotta adjust the levels for black level. I struggled with that a few years ago. Blacks have to be raised. Someone else can likely explain details.
 
Is this why on the same HD monitor, switching between my FCP Apple machine, and my Windows 7 Vegas 9.x machine, that the color rendition coming from the Apple seems to be 'better' meaning a wider latitude of colors and deeper blacks and better black threshold (or am I saying better contrast) than Vegas? If I switch to "Studio RGB" is that going to give me overall "better" color balance on the screen? It seems not. But I'm trying to figure out why Vegas on Windows is so much less even though I have 1GB video RAM cards on both Apple and Windows. The RGB article above seems to say that I should always be using Studio RGB and outputting to Computer RGB when I go to the web. Am I reading this right?
