hi again people . just curious , in DVD Shrink someone said to click on the deep analysis and the error compensating compression ( or something like that ) , does that really make a huge difference ?, it sure takes a lot longer . maybe someone could explain to me what those things do .

The first pass (deep analysis) will gather information on the video content for DVD Shrink to help it to determine in the second pass (encoding) how to use it with efficiency in mind. This will also ensure that DVD Shrink makes it's target size accurately. I highly recommend that you enable this option but do remember, it will make the encoding take a lot longer than without it selected. Of course, there is no substitute for using less compression on your DVD wherever possible.
Compress video with high quality adaptive error compensation: Adaptive Error Compensation exists to reduce the number of noticeable artifacts on the output video. During video compression small errors and artifacts occur, this is not just with DVD Shrink either, it is just one of those bad things about video compression. Adaptive Error Correction was added to DVD Shrink to help reduce the number of video artifacts on the output. With this setting switched on, DVD Shrink will compare the original and the compressed frames to check if any noticeable artifacts have been produced. If they have, it will compensate for them accordingly, hence the name "Adaptive Error Compensation".
