“I´ve had problems viewing my video on PC´s and the quality seems to be muuuuch poorer.”
First off, you should know that a computer monitor won’t display pixels the same as a TV does. NEVER use a PC monitor (laptop or desktop, Mac or PC) to judge the quality of your DVD’s. 720×480 on a computer monitor will not display over the entire screen, like a TV does. If you make the DVD full screen, it will pixelate, because you are actually viewing it at what the video card is set to display.
So —
ALWAYS use a stand-alone DVD player for testing. Sure, make sure the DVD plays fine in a computer, but never judge quality from it. Also, before you commence in burning your DVD in DVD Studio Pro always simulate it – see if there are any major quality flaws with the content you want to burn.
Also, I agree with David. Though, do some tests on multiple players and make a few copies of your own and test those out.
You should definitely get Compressor working again. It has presets for your DVD time length, and those values are set by the video bitrate. So, always export a RAW video file from FCP, bring that into Compressor – choose the appropriate preset (DVD 90, 120, or 150 minute), and this will create an m2v file that DVD Studio likes.
You might have to play with your bitrate settings to get your .ac3 and .m2v file to be under 4.4 GB for a DVD-5 single layer disc. However, the less advanced you are at adjusting these presets in Compressor, the more trouble you get in – it takes time.
Test on a stand-alone, never a computer monitor for quality judgment…and use Compressor.
Hope that helps
