Hi all,
You recall that I was creating this DVD for our basic school.
With my old applications at the end Nero was pushing 2 hours of video on a single layer DVD.
With PD, I'm forced to go for a double layer DVD to have the same result : 2 hours of video on a full DV resolution.

I talked today with the company that will duplicate the DVD for me and they told me this :

"2 hours 5 minutes is the default length for a single layer DVD. If you need a double layer for that duration, it means that you produce at very high bitrates 30-40M... which is not a good idea. Even Disney is working with bitrates of 5 even 3 M for their DVDs , simply because many DVD player will start to stutter at high bitrates. Our advice : keep the bitrate low.. 5-6M at the max."

Back to you guys : I'm in the middle of 2 contradictory point of views...
PD Forum tells me : go for double layer and high bitrates...
Duplication company tells me : avoid player compatibilty and go for low bitrates...

sigh...

there is a problem with low bit rate quality with PD9, when selecting SP or smartfit. Most people (for now) just select HQ and double sided, but burn to folder and use IMGBURN or NERO essentials to reduce to single sided. Eventually Cyberlink will recode their very good 32 bit DVD/MPEG encoder from PD7 and before into 64 bit software (hint hint). The extra step does not take long and imgburn is free ... try it and see the difference.

the HQ encoding is as good as anyone's in the price range or 5x for that matter. RTX 2060 SUPER 8GB GDDR6

All very well for Disney who use a hardware mpeg2 encoder costing hundreds of thousands and have source material which is film or 4K video

Disagree!! Google will let you know a few comparable priced encoders which do a better job. I am a fan of PD9 for HD but it is pretty poor for SD mpeg transcoding. Panasonic SD9, Panasonic TM700, Panasonic SD600, GoPro HD Hero.

I understand that PD9, the encoder MPEG2 (SD), lower than the same in PD8, added to this, only the profile HQ DVD resolution is 720x480 and max bitrate CBR 8000.
So I saved the video to file (Producer) 9000 bitrate when possible and use Nero to complete the job, so that links SmartEncoder to avoid recoding the video
