I edit my videos in HD and

I edit my videos in HD and burn to DVD. Yes it can be done, but not with consumer grade software. With Premiere Pro I edit using an AVCHD 1920×1080 preset and when is time to export I use Adobe Media Encoder. I set the video format either to MPEG2 DVD or H.264 (mostly this one), pixel aspect ratio to widescreen and make some adjustment in the bit rate settings (VBR or CBR). Of course you will lose a lot of video quality, so you cannot expect the original HD resolution. Like Weddingmaster mentioned, you need a Blu Ray burner and I may also add a professional disc authoring software, such as Adobe Encore.
