Greetings! I am very new to video editing and am doing my best to get up to speed. I have the Adobe Master Suite CS5 and, after many years designing for print and web, I am being asked to do more and more video. The last project I was on resulted in mastering a DVD using Encore CS5. It was challenging and resulted in many garbage DVDs until I figured out what was wrong. Is this the software you pros use? Is there something better? Can you make a recommendation? Thanks!
Encore can create professional DVDs if you know how to use it, build it using correctly prepared assets and take the time to test the output. The same can be said for DVD Studio Pro, Sonic DVD and heck, even Toast if you really want to. Scenarist is arguably the "most professional" DVD authoring platform, but there are plenty of DVDs being authored in Encore and DVD-SP that work great and are of professional-lever quality and caliber.
If you have Encore, take the time to learn it and it should serve you well. There is a lot of good info on the COW already, and if you can't find it here, there are good tutorials that can walk you through getting started.
Keep in mind that a lot of what makes a DVD "good or bad" is the encoding and preparation of the assets for the video itself and the menu graphics.
