Can play only half of a DVD

[ghiatti1]

I have bought a new stand alone DVD player, a Silvercrest 6515.
It plays Divx and Xvid files very well but I have problems with some DVDs. I can see perfectly about half of some DVDs (ca. 55 min) then it starts slowing down and displaying green squares and finally stops. My Sony player plays these DVDs perfectly until the end.
I burn at 8x with my laptop and use Verbatim 16x +R , which I think are good quality.
Can it be that the laptop cannot burn the second half of the DVD properly? What can I do?

Thanks for your help

Try another brand of media: The drive in your laptop may not like the disc. Try using DVD-R instead of DVD+R.

Did you change the booktype on the +R to DVD-ROM when you burned it?

Personally, I don't use +R media at all any more for this very reason. Good Burns, correct Booktype, Taiyo Yuden DVD+Rs and they still wouldn't play on as many players as a straight up DVD-R.

Half the burning speed , and stick with dvd-r ... console's dont mind ... but dvd home players do .

Could we suspect the media of these disc that show the problem are either + and / or dl's ???

It would be rare these day's for some dvd players to have issue's with video content near the outer edge of the disc ...
so it might be how much you are jamming on them .

Best try burning with imgburn and see how it gose .

Stick with the rule's and expand from there :

1: dvd-r
2: No more than 4.3gig per disc
3: Burn no faster than 4x

These are the most compatable settings for all players .

As for dl media ... take 8.3gig as example .

In the authoring process the first layer contains 4gig , layer break point next , then remaining 4.3gig to second layer .

The closer the layer break is on the first layer , the less noticable the jump between the layers will be during playback ... or so the theory gose .

As for divx and xvid ... there is a difference ... correctly encoded ... and not .

Find one that plays perfectly ... take it to the pc , and use gspot to tell you the internal information it contains ... and use this information when encoding files to divx or xvid .

As your computer writes the DVD the actual speed it is writing increases because it is moving from the inner tracks to the outer tracks. I'm assuming your disks are single layer since you say they are 16x.

Inability of your system or drive to handle the speed increase could cause these problems.

Since you have not provided any details on your system or drive, we cannot make suggestions other than to check to make sure your drive is using DMA.

I would be loathe to blame the media. Although pixilization of the type you see could be incompatibility of the media with your player, in my experience it occurs immediately. I am not familiar with your player or its chipset so cannot comment on its compatibility.

You have not told us if your computer can play these DVDs without error.

Thanks for your help.
My computer can play these DVDs perfectly and my Sony DVD player too.
The laptop slim burner is a NEC 6500a. It had problems with some Philips DVD +R, which neither my computer nor my dvd players could read. So I switched to Verbatim +R 16x and they work perfectly with my PC and Sony DVD player. The problems started with the new Silvercrest player.

According to the DVD player list (link at left), your player has an uncommon chipset. It appears to be a commodity-level player, if possible I would attempt to exchange it for another brand using another chipset.

I'm a little confused. After reading this thread it seems you're all agreed that DVD -R media is the best. Does that apply to Dual Layer also?
If you go to this page (PGCEdit):
http://www.digital-digest.com/~blutach/dl_burn_guide2/dl_burning_with_pgcedit_v2.htm
and scroll to the bottom it states:
"A point on media – it is highly recommended to burn on DL +R media. The issue is that –R media is not compatible with the standard method of setting a layer break. A –R DL always burns to the end of L0 and breaks there. If you must use –R media, you must complete the dialogue box accurately in step 4 and use ImgBurn to burn. Even then, you’re chances are problematic. Use high quality, +R media – Verbatim is highly recommended (Ridata is not recommended)."
I was planning on using DL +R media but maybe that's not such a good idea? I do all of my dual layer burning with PGCEdit/IMG Burn.

I for one do not agree that DVD-R is the best. DVD-R is the best if you wish to be able to read your disks on antique DVD players.

DVD+R-DL is more stable and superior to DVD-R-DL and the antique players are unlikley to read either DL format. It has also been around longer.
