Which is pleasure to your eyes? - DVDs or MPEG4 ?

[Tuning]

There is a noticable fact (atleast for me), the DVDs viewed over PC is more smoother (not highly-but, noticable) than the corresponding highquality DivX/XviD/RV rip (Obviosly from same DVD). I think its because of high quality decoders used for postprocessing.

As question askes which looks better for you. Please note that there is nothing related to codec/bitrate/noise and other realworld encoding parameters. Just asking what is giving more detail. I do also know that MPEG-4 is a lossy compression method and thus the result will be lossy. ( Still decoders are giving high quality results )
Some might think this is a useless or funny opinion on DVDs vs Mpeg-4. Do anyone have any comments on topic?

BTW, I don't know how it looks in hardware player.

Smoother? Framerate-wise? And why would anyone prefer a compressed version over the original (except if the compressed version has been enhanced, like with sharpness-preserving upsizing) ? I find MPEG4 better than MPEG2, but since all sources are MPEG2 there isn't much to improve the image. That said, I'd prefer it if my DVD source was MPEG-4 at the same bitrate as the MPEG-2 version, but I won't prefer MPEG-4 when it was encoded from the MPEG-2.

Hi mf,

Agree that the created copy to be a perfect one. What do you think on decoding properties ? Won't they enhance the video by postprocessing ?

MPEG2 can be postprocessed too. It's just so that barely any decoders do so (only ffdshow and MPEG2Dec, and ffdshow has broken MPEG1/2 support). And postprocessing is in the case of DVD more harmful than good. Agreed, DVDs have quite some blocks (I have still to see exceptions - maybe I'll once get my hands on a very good superbit release), but deblocking/deringing is usually too destructive for the scenes/picture parts that don't need any postprocessing. Also, a good MPEG-4 rip will have the same problem with postprocessing.
