On the Nosferatu disc the problem was that captures were made to fit a certain aspect ratio using PowerDVD, meaning that the resolution was changed. That is, the DVDs native resolution of 720x576 non-square pixels (which will make the picture appear as having an aspect ratio of 1.25:1 when displayed on a computer screen with square pixels) was reshaped to 768x576 (making the picture be 1.33:1 on a square pixel screen). In PowerDVD this caused, for whatever reason, the chroma effect to appear.peerpee wrote:I really dunno -- we had similar problems with NOSFERATU, and some other titles. Beaver's grabs were just not representative of the MoC discs, and the discs Beaver receives are always finished discs. There's something quite wrong somewhere.
That PowerDVD's reformatting caused the chroma effect can be seen by making captures in the native resolution (720x576), where there is no such effect. Using different software to reformat the picture to 768x576 (to make it 1.33:1 on a computer screen) caused no chroma effect.
