I'm new here and new to video editing, so others will give you better informed answers. While waiting for those, The following may help:
Once you've imported your content into PD, and you've edited it, you do need to "produce" (render) it before you can make a disc.
The format into which you produce/render it depends on how you want it to play. If your computer or video player is capable of playing AVCHD files, then you'll probably want to render into AVCHD or MEPG-4. If, like me, you want to share video with people who don't have powerful computers or video players, then you'll probably want to render into MPEG-2. If using MPEG-2,try PD's default of DVDHQ, and if you're in the US, stay with NTSC. In other words, don't change things at first.
Go ahead and render your video. If it's very long, go have a cup of coffee, lunch, or even let the computer render while you sleep.
Don't worry about SVRT one way or the other. It's a way of rendering which can save time under some circumstances. Turn it off if it seems confusing.
When rendering is complete, click on Create disc at the top of the screen. When that screen comes up, and if you want a DVD which can be shared with folks who don't have high powered equipment, be sure to click on "2D disc" up at the top, and then make sure "DVD" is lit up in light blue (top left of the dialog box). Choose "Best Quality".
If you're aiming for the best looking video and have the capability to play AVCHD, then of course be sure "AVCHD" is lit up in blue at the top of the screen before burning.
Finally, while experimenting like this, consider saving your results back to your HD in a place where you can find them easily. It saves a ton of DVD discs. Also, others will tell you to "Pack" your project all in one place, and I agree with that. After saving your rendered result, and maybe having burned your DVD back to the HD, click "File" in PD, go to Export, and choose "Pack project".
AVCHD video can be recorded onto DVDs, and it palys beautifully, but a DVD won't hold much more than 30 minutes of AVCHD quality. If you want to have a longer video, you'll either have to record on a double sided DVD, or use a Blue Disc and BD player.
That shoud get you started until more knowledgeable people chime in.
