1. DVD-R Version: 0.38
2. Encoder being used: CCE-SP 2.66
3. Using eclCCE? Y, 1.8b
4. Bug encountered:

Chapter stutter.

I authored (with IfoEdit) a new title using just the first five chapters of Donnie Brasco, PAL, R2, in order to speed up the encoding and burning time. The problem is just perceivable in my standalone player, that is a Medion DVD player. It seems to me that the stutter is reduced respect to earlier releases of DVD-RB, but it is there. No doubts about.

The stutter is present at all chapter changes.
It is a pause of one or two frames.
It seems to me the audio is perfect.

As previously reported, I also noticed that in the display of the player, if you play the title normally, both the chapter number and the time elapsed is correct; if you play backward through the chapter breaks, the chapter number is not updated and the time elapsed shows a value that is affected by the following error (in bold the right value to show):

Chapter nr ... Start ... End ... Time showed in backward play through the previous chapter
........1 ........ 0:00 ... 5:30 ... n.d.
........2 ........ 5:30 ... 12:39 . 10:59 = (5:30 - 0:00) * 2 + 0:00
........3 ........ 12:39 . 14:14 . 19:48 = (12:39 - 5:30) * 2 + 5:30
........4 ........ 14:14 . 17:45 . 15:49 = (14:14 - 12:39) * 2 + 12:39
........5 ........ 17:45 . 23:25 . 21:16 = (17:45 - 14:14) * 2 + 14:14

The encoded frames, showed by CCE, are right for all chapters; the overall quality of the encoding is beautiful, so I do not think it is a problem of bad encoding...

Regarding the environment clean up proposed by lab-one, please note that I have just a single AviSynth installation on my machine, Version 2.54, build: Jan 26 2004 [09:28:02] and regarding mpeg2dec3dg.dll, I had already cleaned up my environment. Actualy just two instances of this dll are present (one in the plugins dir of Avisynth and one in the dir of Dvd2Avi, and they are both the same file); no instances of mpeg2dec3.dll are present.

I did'nt perform a radical removal of antivirus and of all other applications present om my PC, but in a couple of days I will have available a new PC without any software installed, where I will just first set up DVD-RB and test it alone.
