Color "chunks"

[jkapa]

Has anyone noticed "chunks" of color appearing while watching a dark scene on your DVD player?

I´d like to know what´s the most likely guilty part: dvd player, S-Video cable or TV (Trinitron bit worn out).

I doubt it's your cable.

It MIGHT be your TV. Who makes the DVD player?

Macro blocks. Comes with mpg compression. The lower the bit rate, the more obvious the macro blocks.

It´s a Pioneer and one of the good ones 2-3 years ago.

I don´t think they´re macro blocks. This happens on comercial DVD´s even the one´s that have great quality and only in dark scenes - if it were macro blocks shouldn´t it be visible in all mono color scenes and fast action scenes?

Hmm, no obvious solution then.

Have you tried troubleshooting it? For example, have you tried hooking it up to different TV's?

In my experience - no. Macro blocks are (to me at least) most visible in dark scenes, specially in the background. Even commercial DVDs use the same compression method as the ones you and I make, so they suffer from the same problems. The higher the bit rate, the less noticable are the macro blocks of course...

I agree with the above, if I try to cram a 2hr plus film to one dvd, i get the blocks
