Bloody artefacts!!!

[Cris_Go]

I reauthored a DVD (DVD lab Pro 1) with my translation, in my language and the resulting movie after burning is with some artefacts, unlike the movie on HDD which is clean. I recoded the movie with different programs (Nero Recode, DVD Shrink with advance analyses), still nothing better, just the artefacts are moving to another places on DVD.
What can I do to correct this problem?
PS. The movie as data is smaller then DVD blank, so there is no problem of compression.

what kind of artifacts?

Enf...

...Sometimes, coloured squares, sometimes green squares on the screen. Watched on PC they didn't appears, unlike on SAP.

If the burned disc played back with artifacts on your standalone player, but without artifacts on your PC, your standalone DVD player might benefit from running a DVD/CD cleaning disc on it. Maxell makes one that sells for approximately $10 US...

I'm not sure if you mean burned DVD plays good on PC, or you mean DVD layout prior or original ripped DVD on HD.

If burned disc plays good on PC, as suggested try cleaning, or new brand of blank disc.

If you're using recode or shrink have qual at 100 so no re-encode, or use demuxed video direct from vob.

Only other guesses would be what is the bitrate of mpg2? Does the original play in your sap, if you still have access to it?

1. Burned DVD plays good on PC.
2.Clean the SAP lens. Done before these posts.
3.I did use demuxed video with DVD Decrypter.
4. The original play on SAP. About bitrate; I don't make changes to original movie as usual.

PS. I forgot to tell you: Resulted DVD with artifacts play the same way on SAP of a friend(different brand).
Thanks for reply!

The burned DVD should just be a copy more or less of the original, and the original plays on SAP (2 of them), and everything plays using PC's DVD drive...

About the only thing left is the media I think. Your PC's DVD drive is better, more precise and more forgiving then the average SAP. Think you just got bad media -- there's a LOT of it out there --I'd say try a good, known brand (many like Verbatum), if only buying a couple of blank discs to see what happens.

Unfortunately, this is not the first time when it happends this; I tried with different blanks.
I made, not once, and I succeed to recode a movie from a duall layer disc on a single layer disc (initially 6.4 Gb). Now, I can't understand how it happends that a movie smaller as data then a disc could not perform normally. (Personally, I suspect that the rate of compression is guilty for all of these).
I own two DVD burners: Sony U 18A patched to DRU 700A and LG 4163B ver. 101 patched to 104 and I tried with TDK and SKC blanks, before and after updates for drives, still the same results.
...Verbatim blanks -in my opinion- are the best no matter what type CDs, DVDs or floppy, but somehow here are hard to find, as DVDs...
Anyway::thanks:

As a final suggestion, if you're not already doing so, try limiting the burn speed to 2X or 4X...

If you're stubborn like me, and still determined...:)
I think I'd first try re-writing m2v files by passing through TMPGenc mpgtools. Whether mux/demux not using audio, or edit & cut a few frames etc... This should re-write headers etc. & has brought bad video into spec for me many times without re-compression.

Maybe this is the final solution! Thank you for your advice!
Wish you all the best!

I found the solution: (the bitrate was guilty for all troubles) I used "SolveigMM MPEG2 Requantizer" to decrease video bitrate. The resulted movie is good without artifacts with no evident quality loss.
