NERO Media Quality DVD Test Results?

[kattz]

Hi! After having some prob. w/ my dvd player reading burned discs, (playback would freeze, & then resume) I decided to use the Nero CD Test pgm. Results of one disc are posted below; However, I do not clearly understand the test results! I read/reread the help files in Nero, & they do not seem to correspond with the program...

What version of Nero are you using and what kind of disc... Data VCD, DVD ?

[kattz]

Nero Vers. 4.51.1 - it is just the cd/dvd tool, not the complete program.

I am working w/ dvds. I have been told that my firmware may need to be updated, so I have been checking into that...

BTC drive is not the best scanner drive.

Updated firmware to lates rev.0060. Scan after latest burning[/img]

If I'm seeing correctly - it looks to be verbatim media. If so, that doesn't appear to be the problem. The BTC 1008 is only an 8X burner - just because it can burn at 8X doesn't imply the burn will be perfect: Even if it will complete the burn without crashing.

I would recommend burning at 4X with that particular burner, then scan with NeroCDspeed - see if that improves things.

If you're committed to burning at 8X, install a 16X drive, many excellent choices available for $40 to $45 shipped. (i.e. NEC, Pioneer, LiteOn, etc..) A 16X drive will do a clean burn on 4X media (i. e. Taiyo Yuden) at 8X - I've seen it.

As to the scans: I look at two things: #1 Quality Score - less than 90%, it goes in the reject pile, probably accounts for less than 5% of the discs that I burn - typically less than 3%.
#2 Spikes at the end (outside) of the disc - indicates potential problem with playback, usually results in a lower quality score.

Your scan indicated the burn went to the edge without a problem, but with overall poor burn quality - IMHO the disc was burned at too high a speed.

I normally burn at 1/2 the rated speed of the burner: I.E. Plextor PX712SA (8X) burns at 4X; NEC 3520A (16X) burns at 8X; Plextor 716UF (16X) burns at 8X. This usually results in many fewer bad burns.

Hi classfour,

Verbatim (up to 16x) is the media. The burner automatically reverts to the burning speed that it wants to use, which with this meda was 2x. After I did the firmware update, it started burning in 4x... I did a transfer rate test & it provided me w/ the following results:




also did test w/ dvd infopro...
