There is a recent thread by Gossamer on burning AVCHD to DVD-Video. You might want to Search this forum for "AVCHD" and filter on People>Gossamer.
Now, tell us more about your exact source footage. That might make a difference.
No, From Premiere Elements its not possible to burn a HD DVD directly.
Are you talking about High Definition video as written to Blu-Ray or the actual HD-DVD format??? HD-DVD is a dead format, manufacturers stopped making HD-DVD drives/players/burners almost 2 years IIRC, you can't buy HD-DVD players or burners in stores anymore, though you can find them on eBay... & unless you're making these DVD's for yourself, you're really doing a dis-service to anyone you give them to. No new software is going to support HD-DVD simply because it is a dead format, on the other hand all modern video editing software supports Blu-Ray. Even HD-DVD blank media is becoming extremely hard to find, many of the major media vendors don't even have any left in their inventory. All of these factors are driving even the most die-hard HD-DVD advocates to Blu-Ray... even the might of Microsoft wasn't enough to stave off HD-DVD's death.
Now if you were talking about High Def video written to Blu-Ray... I don't know about Premier Element 7, but it is definitely supported in Premier Elements 8.
As ChaosdsmFL said in Premiere Elements you can not directly burn to HD DVD. However you can burn your 1920*1080 file format videos via Burn to Blu-ray option. Go to Disc->Bluray and choose the preset 1920*1080 (PAL/NTSC and encoding as H264/MPEG2) and burn to blu-ray.However there is no option in PRE to burn this size video to DVD and retain the quality.Burning to DVD would result in bad quality .However burn to blu-ray will provide you with the sharp quality.
Thanks for the response Allen...I realized after I posted that this is
what I would need to do.... One more question if I am to stay with DVD
quality for the time being, should I set my video recorder to a
resolution less the 1920*1080 so that it might look better on DVD media?
Good question... The resolution of standard NTSC DVD is only 720x480. However, finding a resolution to record at on your camera is very dependent upon other factors. 95% of those factors would be how well your camera handles downsizing video Vs how well PrE handles downsizing video.
I would suggest a simple test, set up an area with several different objects of different colors, sizes, shapes, & orientations, then shoot 5-10 second clips at all of your camera's various resolution settings. Import the clips to PrE & burn them to DVD, then watch the DVD on your TV. This will show you the differences between how your camera handles down-sizing the videos Vs how PrE handles downsizing the videos. Just be sure to add a text lable in each clip before burning to DVD showing what resolution that clip was shot at, so you'll easily know what resolution works best for your camera. If you don't notice much difference or very little difference between clips, then both the camera & PrE are performing the same job at about the same quality level,
Good suggestions, I will give this a try. Like you motioned, there might be a difference the way Pre downsizes (dithers) video resolution....
