DVD Shrink / Deep Analysis

[Rail-Runner]

Wondering if there will be any plans in the next version of DVD Shrink to allow deep analysis of the same file numerous times at the users disscretion, I have found some brands of media preform better if this option is available at all times, at times you can get a bad original backup due to a media problem, then it will not allow use of Deep Analysis again from the Decrypted file a second time or the smaller Shrink file if it has already D/A, this would be a nice option available at all times of DVD Shrink.

Unfortunately, DVDShrink is no longer being updated (except for bug fixes).

huh ?

bad original or bad backup , which is it ? if you mean a bad backup because you burnt to crap media then that has absolutly nothing to do with DA.
if DA has been done once it doesnt need to be done again from the same source, the data doesnt change. and why would you try to DA already shrunk files ? pointless.

I have found a difference in error rates when D/A is applied to the same media and when it is not useing the same Shrink file.

DA has absolutly nothing to do with the burning, period, so in no way can effect the burning, period.

DA analyses the original stream to see what frames have more dct coefficients and which less etc. the theory being those with more can have more removed with less visible difference than those with less having the same amount removed. this information is stored the first time you do DA ona dvd so it never has to be done again on the same dvd. so again NOTHING to do with burning.

so if you are seeing dvd lasting longer when DA is used and dieing when not its an abberation. :)

try instead using better quality media and burning slower(such as x2 at most).

So you are saying a D/A of an already Shrunk file of 4.35 GB will not be enhanced any further dureing encodeing before it writes. I use Ritek GO4 and GO5, the GO5 with hub# J3-02L are not there best and are suspect, I`m useing Pioneer DVR-109 & 108, so why does the Shrink allow a 2nd copy from the 4.35GB file with D/A,unless this further smooths out this compressed file. P.S. I only burn at 4X. Better get some more Bubble Gum.

unless you are reducing the size again there is nothing for DA to do. so going from 4.35gb to 3.0gb yes DA will help but going from 4.35gb to 4.35gb what do you think its going to do ? no coefficients etc are being removed so the DA information is of no point. even if you decide to go 4.35gb to 4.34gb DA is only going to make a tiny,tiny difference which you would probably never be able to tell.

yes i have seen reports of bad and/or suspect ritek batches aswell. seems they got so popular they started selling some of their B grade dvdr's aswell.

P.S. I only burn at 4X
burning above x2 has been discussed on here many times. some people have no problems while others players and/or dvdr's simply dont always work right. try burning at x2 for awhile and see if the problems start to clear up.

If I remember correctly some of the GO5`s won`t burn below 4X pretty sure they were hub# J3-01L which always burn OK, While the J3-02L were the ones giveing trouble at 4X, Thanks for the tip maybe it will help this batch.Checked again the J3-02L won`t burn below 4X either, guess I`m stuck with 150 coasters that I got from BLANKDVDMEDIA.COM and now he`s jerking me around about exchangeing them for GO4`s

[sweetness]

i have some GO5 that burn under 4x. i think i has to do with the burner too. my 4x LG burner will only buner ritek G05 at 2x.
i think they don't like each other.

[Rail-Runner]

You bring up a good point about the available write speed of different burners, but I also think they have changed the available write speed of the GO5 -R 8X Hub/Printables lately to include writeing at 1X and 2X, I seem to recall 4X was the minimum write speed on the batch I received a few months ago from the websites info. As I write this BLANKDVDMEDIA.COM has replied to my email to complete this exchange for GO4`s. I will keep everyone posted as to the outcome.

BLANKDVDMEDIA.COM has replaced the defective Ritek GO-5`s with 250 GO-4`s plus 20 photo glossy sheets of paper, they take there customer complaints seriously and find an acceptable solution.
