DL burning unreliable LiTeon dh20a3p, how to improve results?

Hello

I’m new to burning DL DVD’s.
During a week I have burnt with Nero 8 5 video discs of which 2 are poorly readable. Writing speed 8x.

So it appears that while DL media is expensive to buy it turns out to be even more expensive if to count only successful results.

My burner LiTeon dh20a3p fw: xp5r in external USB enclose has served me well for 2-3 years already.
But seems that isn’t upt o the task when it comes to writing a DL media.

Below is description of one poor performance DL disk as seen after burning with ImgBurn.

Does it tells some words of wisdom, how to improve results?
Any common suggestions?
Which is now the most suggested DVD writer drive?

Hi,

the only reliable DL media is Verbatim.

Last time I have checked Verbatim was single layer +R media 2 years ago and then Verbatim was an absolute crap. Of 10 burnt 2-3 were coasters, even when burnt on different burners. When I switched to SL +R Imation or Intenso - of 25 burnt 1-2 fail.
Perhaps things have been changed now and I should give Verbatim another try once again.

20A3P is an excellent drive to burn DVD single layer at any speed. The quality of Dual layer burns is the total oposite: awful. The very bad quality of DL burns is not related to any specific media.
