here's a funny one

[masterkulgan]

I have noticed the following phenomena while burning to dvds:
about half (from the center outwards) is burned with 1 color intensity and the remaining half with a different tone, and finally the remaing unburned part - now whatever is in the first part plays OK (for about 2Gb) but the second part cannot be read.
I've tried all the tricks (ASPI, Nero settings, etc.), and am willing to post my log, but not to trouble you all with that, am wondering if any body can think of something without further info?

wat media r u using n did u used a higher speed than the media supports?

 

[masterkulgan]

Ricoh media which is the same as is the dvd-burner, but that is beside the point.
I am wondering if it burns OK for half of the disk, why does it change the writing mode halfway?

but that is beside the point

is it media could be the problemo

Sounds like a Zone-CLV burn (4x-6x-8x zones), where it is not a good match to the media at higher speed.

If you set 8x, is still has to start at the lower speed.
If you set a 4x speed and got this result, I would be surprised - in fact, on that showing, I'd say try setting at 4x.

Which drive model, and what media ID?

DVD Identifier should be able to report the ID

The burner is 4x maximum. The media is 1-4x. Will try the identifier, and also the lower speed setting - 1x,2x, and inform of the results. Thanks, I now have something to try out this weekend.

the answer is in your statement of burning at lower speeds

if you wish to burn a disk at faster speeds use better quality media

and the ring problem will dissapear

 

[masterkulgan]

Well, I found out that I cannot change the burning speed - once I insert a blank DVD - the speed setting grays out and is fixated at 4x. Ideas?

What writer and media is it?
That ID program will probably name both.

AFAIK Interaxia is the company formerly called Vivastar, which were forced to change their name due to licencing reasons.
Despite the swiss origin, their media are of rather poor quality, and the actual manufacturing site is obscure.
