Film good then jerky then stop

[grog]

Hi - I have been making a backup of Disneys Hercules as my daughter likes to chew the DVDs...(Im serious)!!

However, I have the following problem :-

ripped from DVD - all ok
rip redundant audio and sub tracks - all ok
ReMpeg the Video stream to 90% Bitrate - OK
Remux - All looks fine
Grab VTS vectors and create new Ifos - still OK

Play first 8 chapters with no problem whatsoever
All the following become incredibly jerky and starty stoppy (Another of my daughters phrases) This leaves the film completely unwatchable. Thankfully I havent burnt this to a DVDR yet -

Additionally - the M2V file plays fine


ANY help would be greatly appreciated !!!!


(Just for your info - The films on the original DVDs become very jerky after they have been excessively chewed by the daughter)

Not sure where you can insert this step, but maybe it has to do with angle pointers. See this thread. I was getting jerking and blocking and the posted fix worked for me. Also, I take it that you are getting this result from the Burned DVD, how about the HD version through a software player? This would rule out a bad DVD, or burning problems. (we all have those burning and itching problems from time to time:0)

Roveer,

i am having exact the same problem with snow white :( burnt it on the same media and ripped it the same way as i have done all my others but 30-35 mins into it starts stuttering and eventually becomes unwatchable,wander if its some sort of new protection or something or maybe smartripper and dvd decrypter cannot decrypt some of the files,i have burnt it 3 times twice on rw and once on a apple so its not the burn,i havn't watched it from hd yet though and i dont really want to sit and watch snow white for 35 mins to see if it works or not

make sure you "get vts sectors" as you very last step.

One possibility would be that they might be reversing the field order in later sections of the MPG file.

Since field order is just a flag in the MPG file that either sets odd or even, they could conceivably set their encoder to reverse the field order and toggle the appropriate MPG flag every few minutes.

Would be a sort of annoying DVD protection now that I think about it - although nothing that a software update to track the field ordering wouldn't fix.
