Quality on DVD burned disks poor

Hi, I am trying to figure out how I can burn a DVD disk that will give me good (HD like) quality and play in your average DVD player. I've been struggling with this for some time and have a fair pile of "coasters" now.

I've read in the forum that this is not possible in PD unless I use BD format, however this does not make sense to me as I now play 'store bough' movies on my DVD player who's quality is great. I've tried using (source) both mp4 and m2ts (avchd) file types both 1920x1080 which look great played on their own, but both seem to have the same poor quality when burned to disk!

I see that there are discussions around this (see: http://directorzone.cyberlink.com/posts/list/1163.page#4317), but none I've seen provides a solution. It seems that there must be a way to produce a disk with high (HD like) quality similar to the "store bought" movies I mentioned earlier, or is PD 9 just not capable of this?

Ultimately, I am trying to produce a DVD that has a menu giving an option of selecting from three short clips.

Look forward to hearing the definitive solution.

I would image the commercial DVD's use a higher bitrate. I think PD uses 8000 by default for DVD. I don't know if creating a custom profile will help. I believe this was discussed, but I don't remember what we came up with. That's where I would start.

I have noticed that starting with a 1080 format and converting down to DVD still gives a better result than using standard definition from the start, but you are not likely to get full HD quality. __________________________________

Standard DVDs are limited to 720x480 pixels resolution.
If your Videos on the timeline have a high bit rate, greater than 8 Mbps, then you get the maxium bit rate burned to the DVD.
A standard DVD's bit rate is a max of about 9.8 Mbps. PD uses about 8 Mbps if the Video bit rate is there. Less if the Video bit rate is less.

That said, if you start with a very clean, noise free video 1920x1080 greater than 10 Mpbs bit rate and have that HD video on the timeline when you switch to the Create disk module, you will get the best that can be burned to a Standard DVD and play on a Standard DVD player.

You can never get 'HD' quality on a Standard DVD.
You can get a clean, sharp as possible Video on a DVD. But it is still a SD video in the end.

In my experience here, I can only full quality on DVD-Video.
Using bitrate 9000 kbs. What is the maximum that the program accepts the other, in addition, whenever possible use the progressive mode.
-----
Limitations of PD, 8 kbs maximum bitrate, interlaced mode has no way to select the progressive mode when in Disc Creat, option DVD.

I completely disagree with all of you ladies/gentleman.
In my opinion the problem is in PD9, precisely speaking in poor MPEG encoder.
Let try and compare:

Option 1. create DVD from AVCHD project even in the best settings as possible
Option 2. create AVCHD disc (to folder) and use m2ts file as a source for multiAVCHD or MediaCoder application

You won't believe your eyes, how bad is option 1

Hi,
"bankroot" please re-read Carl's post:

When comparing these two elements or types of disc you are effectively looking at "chalk and cheese". One disc is SD (NTSC = 720x480 or PAL = 720x576) and the other HD @ 1920x1080. Yes they're going to look different. "bankroot" you are not providing comparable information.

Sorry, but you did not understand my post, because (probably) I wrote it not too precisely.

in Option 2 I meant to create AVHCD disk folder for creation m2ts file in STREAM folder.
As I wrote this file SHOULD be used as a SOURCE for multiAVCHD (it can create DVD disc or folder) or MediaCoder FOR ENCODING to MPEG2 file.

In both options we have rendering to SD resolution.

Especially see on the edges

, you will have breakdown how PD9 encoder do a bad work

Thanks bankroot for your clarification.

OK, this is a PowerDirector forum and I'd like to draw your attention to a Readme guide: http://forum.cyberlink.com/forum/posts/list/13638.page

Read the sections in red please

OK, I knew this restrictions and very sorry for my opinion.

For recap:

MPEG encoder in PD9 (in almost all "cheap" NLE's) is very imperfect, so it was my goal for all my posts in this thread, for me it is VERY strange that freeware do it better

Sorry again, but I think that nobody shoud complain of poor quality on DVD materials made of this NLE.

Whilst I know that we are not meant to mention other software, but I would like to point out that I still use PD because I can use freeware tools to overcome the inadequacies of the mpeg and h264 encoders (because they are crap after all).
PD has an excellent front end but has problems behind it and freeware can improve the final outcome. As a freeware tool, these mentioned programmes are in no way an alternative to the excellent editing abilities of PD and thus should not be a threat to their business but a resource to be utilised to make sure users can continue to enjoy PD and stay (relatively) happy customers.
