Many claim about low quality of burned DVD's. The usual answer is: burn in 1920x1080 ...

My problem when burning DVD's with PD10 is not a lower quality image, but blocks that appear when viewed with my DVD player. When viewed with PowerDVD on my PC I have many small flashy colored blocks on the botttom of the screen.
It seems that the rendering engine and my new PC can't work together.
All drivers have been updated, including the one of the internal LG Blue Ray/DVD writer.

The problem was allready present with PD9, so I upgraded to PD10. Problem remains.
Producing HD Mpeg2, WMV or AVCHD works perfectly.

I have a second PC with PD10 that burns perfectly well DVDs, no blocks on the screen.
However that PC ( I5 with 4GB RAM, slow HD, 17" LCD) is weaker for HD video editing. My imported files are 1920x1080i.

Who has an idea to have rendering with no blocks on my super fast I7 PC when burning DVD's ?

Good to know: when producing mpeg2 files 720x576, I have many thin lines on the borders that make a mess. Rendering problem as well. However mpeg 2 in 1920x1080 is perfect.

In the meantime what I do is editing in PD10 with my fast PC, producing in mpeg 1920x1080 and use my good but slower PC with PD10 to import those heavy mpeg files and burn into nice DVD's, since this slower PC offers a good DVD rendering.

Last but not least: the reason for making low res DVDs is to make a present of edited movies to my family to be viewed on DVD player.

Question 1: what's wrong with my fast I7 PC with DVD rendering ?
Question 2: is there a loss of quality of image when editing from my 1920x1080i cam + produce mpeg in 1920x1080 and finaly burn DVD's ? (instead of burning directly DVD's ).
Thanks for help. Win7 64bits - Intel I7 2600 - 16 GB RAM - SSD 128 GB - HD 2T - GTX 560 Ti

Hi,
Try turning off 'shadow file' in the option menu when burning and also try lowering the burn speed of your burner..see if that helps.

p.s But some RE writqable DVD's for experimenting saves a lot of coasters making

Thanks for your advice.
I turned of "shadow file" + reduced speed to min = x4. Problem remains.

In order to save DVD's I decided to write to file instead of burning. The result is the same when viewing the created DVD files on the hard drive: small squares, green, purple, ... !

have you updated your Graphic card drivers?..Don't use windows update..but go to your Accelerator Card manufacturing sit either Nvideo or the AMD site

Hi Biacman -

Silly, I know. There shouldn't need to be workarounds!

I've come across various ailments with PD10's rendering in MPEG-2 DVD HQ... produced file & burnt disc. The same problems don't occur when rendering in other MPEG-2 profiles.

Try:
1. Produce video to MPEG-2 BD 1920x1080 (should be free of artefacts)
2. Insert produced file into new project
3. Burn > Create a folder (not burn to disc)
4. Use a dedicated disc burner (like imgburn) to burn your final disc.

Cheers - Tony

Have you tried with all Hardware Acceleration turned off?

There is HA in the Produce module and HA in the Burn Disk Module, turn off both, (uncheck the check box).

I do not know if that will help anything, but it is something to try.

Thank you all far the advise !

Hi ynotfish,

Your method certainly works, just as I'm using another PC for DVD burning.
This method is to be compared as "The front door of the house has something wrong with the lock. I'll get in through the kitchen window! "

Carl,

After turning off the hardware acceleration the burned DVD plays well in the DVD player! However still colored squares when viewed with PC with powerDVD.
I hope it plays well in my parents DVD player... it is supposed to be for them.

Would you know what exactly means hardware acceleration ? Does unselecting it affect speed of rendering?
It is possible to select acceleration with OpenCL. Is this acceleration with GPU ? As I have a fast Nvidia GTX 560 Ti, could it be usefull to select OpenCL ?

Hi Biacman,
I have the same Graphic accelerator and downloaded the latest drivers for it and experience on occasion the same problem especially with the 1920x1080 HD output but does burn to DVD/BD disk excellently. I think it is a card problem...if I stop or pause the video sometimes that clears the picture up.

Yes, turning Off Hardware Acceleration will affect speed of rendering. It puts all of the rendering load on the CPU.
Depending on the speed of your CPU, you may not notice a lot of speed change. Or you may see a lot longer time.

HA is the GPU hardware, not only the card but the software installed. That is one reason for the recommendation of updating your Video Card Software from the manufacturer.
