Playback Quality vs. Burn Speed

[djjangelo]

Is there a correlation between playback quality (or dvd player compatibility) and burning speed?

I'm burning with Nero (UDF/ISO Mode) at 4x using Ritek DVD-R 4x media and everything seems to go fine but I often get playback errors (especially in later chapters) on standalone DVD players.

Would reducing the burn speed to 1x solve any of my problems?

I've often seen posts regarding this, but never including any proof positive that this assertion is valid. The simplest suggestion to you would be, using the identical media. burn TWO DVD-Rs of the same DVD source at two different burn rates - and see for yourself if it yields differing results...

My burning speed experiment:

Materials:
1) Ritek 4X rated DVD-R (2 identical discs)
2) Xbox DVD Player (v1.0 w/Thomson Drive)
3) Burner/Computer (see my sig)

Procedure:
1) I burned the same exact movie in the same manner but onto two different discs of the same type, one at 4X and the other at 1X, using Nero 5.5.10.42

Results:
1) The disc burned at 4X jumped, stuttered, and digitized in the last chapter
2) The disc burned at 1X played fine throughout the last chapter

Conclusion:
1) Burning speed does matter, or at least it does when you’re attempting playback on an Xbox.

In the NERO settings for "UDF/ISO" mode did you, under the "UDF" tab, remember to put a checkmark in the box labelled "Force DVD-video compatibility mode (required for Xbox TM)"?

Did you also make certain (same tab) that it's set to "UDF 1.02"?

[djjangelo]

Yes, I enabled the "Force DVD-video compatibility mode (required for Xbox TM)"... (when you do this it grays out the UDF partition type and file system version)

I burned both discs exactly the same way. The only difference being the burn speed.

It would seem that you now know this with certainty.

However, I'm guessing that your curiosity will get you enough to cause you to take the DVD you burned at 4X somewhere to play it on a standalone DVD player ;>]

I like to add some remarks.....
burning speed sometimes does matter as the physical "pits and lands" are defined more precisley at lower burning speed.
especially if it comes to play that discs on standalone players.
(of course depending on the writer and laser power calibration).

the next remark has nothing to do with burnspeed but with processing speed. DVDshrink offers good results in compressing
a video,,, but when you are into that quality wing I suggest
professional mpeg encoders or a compression tool that uses
another kind of masking .... like "instant copy".....

"Force DVD-video compatibility mode (required for Xbox TM)"
... Does anyone know what exactly this setting does?

Yep, I went ahead and tried the two discs on a couple of standalone players and got the same results. The disc burned at 4x jumped and stuttered, while the disc burned at 1x played fine...

Along with enabling UDF 1.02, it will burn over 1GB of data to disc, as far as I'm aware. This must be an issue with the X-box.

Do you mean if I attempt to burn a DVD with only like 600Mb of data it will go ahead and fill another 400Mb with arbitrary data?

Is because some systems (like the Xbox) only like to see DVD's with at least 1 Gb written to them?

[The Edge]

In a word, yes.

OK, I just tried my disc that I burned at 4X on my friend's new Sony (which is supposed to have very good "error correction") and it played perfectly. I'm talking about the same disc that skipped and stuttered on my other standalone.

My next question is: Where did all these "errors" come from? Is it my burner's fault? My PC?

[empiror22]

I have backed up about 300 dvds and have found that speed and play back atleast for my panasonic s82 and sony s315 s615 don't matter (with "good media" ) my xbox has problems playing back ups faster than 1x. i think its the player ( standalone) what the model if older or cheaper player the "read speed" may be slow

[peterggg]

"good media"

Empiror22 refers to "good media". A friend is just getting into this and was wondering if there was a significant differnence between the various storage media. Are all blank DVDs created equal? Which are the real winners? Which are the best value?

I guess this thread is for DVDs but if anyone has an opinion on the above questions but for Mini DVs I would also greatly appreciate it. Thanks.
