How do you increase DVD Shrink's compression to achieve 4.6 GB

[Firewire60]

I have had two instances recently where I have tried to make a 4.6 GB DVD by using NeroVision to make a menu for three MPG hobby movies (mpg files) and then converted to VOB using NV.
All went OK with NV but when I tried to shrink the compilation to 4.6 Gb with DVD Shrink It gave the message towards end of compression that it could not continue. It seems that it was unable to achieve the required compression because when I shrank two of the movies with menu or the other one with menu DVD shrink completed the operation OK.

Simple answer is to put fewer of the movies on DVD but I wanted to combine these three.
In total they came to about 6 GB before DVD Shrink tried to compress them.

Is there any way of allowing DVD Shrink to achieve this extra degree of cpmpression.

I believe that all of the VOB files were error free and shown by DVD Shrink being able to shrink smaller groups of the movies.

Any suggestions

I'm not sure what you are doing, but a DVD-5 has a capacity of about 4.37GB, so that may be why Shrink doesn't want to make the DVD.

use DL media!!!! and compress nothing!!!!!

encode the mpeg at the correct bitrate to start with is the best solution

Redwudz, Shrink is doing its own thing trying to shrink the movies to the appropriate size for a DVD-5. it sets the target size itself but was unable to achive the compression apparently.

GJ-M Not sure what you are saying about encoding at correct bitrate in first place. All foreign stuff to me. neroVision will process the MPG files and prepare a menu and convert to VOB files and Shrink will compress two of the movies together but not three together to fit on a DVD-5.
Perhpas the three movies in both instancesa are just too big for Shrink to copmpress them adequatley to fit on a DVD-r.

DVD Shrink sets the resultant compressed size itself as far as I know to fit on a DVD-5. I don't set that.

Quick & dirty solution ... Shrink the movie to a new folder (maximum compression ... ignore the size overflow message), then just run Shrink AGAIN on that folder to re-shrink a second time to the correct size!

Firewire60, just making sure you understand that the size of DVD media is measured differently by different programs. Likely the problem with Shrink is that there is nothing left to remove to make the file smaller. Commercial DVDs are made at a high bitrate and have video information/frames that you are not likely to miss. Shrink tries to remove those. But there is a limit without damaging the running of the video.

DVD Rebuilder can re-encode the file and reduce the bitrate, instead of just deleting frames. Usually better quality this way.

NV is not a very good option for authoring or encoding. Better would be to use a bitrate calculator and a decent MPEG-2 encoder to start with, and you shouldn't have to use Shrink as the total size of the videos will be correct in the first place. I imagine that's what BJM was saying.

I think you are running into some of the limitations of the One-Click tools. You might study the guides to the left: CONVERT and AUTHOR to see some better ways to do all this with more control over the end product.
