One quick question:

"Output YUV Data as basic YCbCr not CCIR601
This affects the range of values accepted for luminance and chrominance signals. YCrCb is raw samples, taking the range 0-255. In TV systems CCIR601 is normally used, which restricts the allowed range to 16-235 for luminance and 16-240 for chrominance signals. If you are mastering for TV (e.g. VCD, SVCD, DVD) then do not tick this option.

I make my SVCD's to watch on TV with a standalone DVD player.

Okay, so in TMPGEnc, I DON'T want to tick this option?

For a while now I've been encoding with it on. Seems to make the image a little darker (now that I think of it a little too dark in some scenes ), but the colours are more accurate... tradeoff I guess.

Any recommendations?
