large digital blocks appearing in shrunk movie

[saxmanet3]

OK,

I am having a problem with the quality of the final DVD. When I have used DVDShrink or Nero Recode2 to reduce the size of the DVD, the quality seems fine ON THE COMPUTER. So If I play the movie from a folder using the player in ifoedit it looks great. When I use ifoedit to create the image and then use Nero to burn it, the final DVD now has frequent places where large digital blocks flash across the screen. Sort of like when a thunderstorm is interfering with your satelite signal. I thought that was called "pixelation" but reading other posts, people are only seeing pixelation at 400% zoom. I must be seeing the effect of missing data! The final DVD does this on my home DVD Player as well as a software player. Does anybody have any ideas?

AMD 2500+ 1GB DDR 333 Ram
HP dvd200j writer (latest firmware)
ifoedit v0.96 to burn image and view dvd
DVDShrink 3.1.4 for shrinking and alternatively nero Recode 2 (latest)
Nero burning ROM (latest) to burn the image to dvd
Memorex DVD+R 4x media
Home DVD player is a Sony DVD/VCR combo :scared:

Hi,

This problem is related to burning or simply bad media. Try using different burning software or better quality media (such as Ritek).

I thought that Nero was one of the best programs to use. There certainly is a lot of references to it throughout Doom9. What other do you suggest? Also, while my Sony DVD player will not read my earlier backups using Verbatim Media, it has not problem with memorex. I have not seen very many kinds of media in Best Buy, so I guess I need to search the web for the best kind of media and order it online. Is Ritek the best choice?

If you can't get Verbatim to work, you better call up Houston,I believe you have a problem:(

Hi,

I've re-read your initial post. Why use ifoedit? Shrink produces files that are capable of burning with Nero without doing anything with ifoedit. You could be introducing a problem by incorrectly (or needlessly) using ifoedit. I suspect this may be the problem, since you say that the final dvd has problems with a software player.

The problem you have with verbatim media highlights that your player is very picky about media. I've had good success with Datawrite grey 4x -R, Ritek G04 -R, Ritek +R (BTW I have a Sony DVP-905).

You also have to consider the size of the DVD, I played with copying "The Green Mile" which is almost 3hours and both IC8 & shrink-recode2 left alot of microblocks in the darker parts, this movie or other DVD's its size should probably be put onto 2 disk or use maybe CCE or just watch the original Dual layer disc of it!

I went ahead and tried to burn directly to disk bypassing ifoedit and the result was the same. I am going to order some Ritek dvds and try them.

Yep "Alurker" is 100% right ;)

If you do a movie like LOR2 (almost 3 hours) with Shrink or Recode2 the results will be a lot of macro blocks ( low bit rate ).
The only way to produce a good copy of those types of movies ( more than 2 1/2 hours ) is using a really good solution like CCE.
For example the LOR2 with a AVG bitrate of 3100 using CCE was very good ;).
The backups done with the other programs where garbage ( better using the DVD9 version ).

Quoting saxmanet3:

"the final DVD now has frequent places where large digital blocks flash across the screen. Sort of like when a thunderstorm is interfering with your satelite signal. I thought that was called "pixelation" but reading other posts, people are only seeing pixelation at 400% zoom."

This doesn't sound like macroblocking to me. Saxmanet3, you could prove if is a transcoding problem by transcoding at 100% in shrink (use the reathor & start/end function to make it fit).
