Problem with glitches/blockiness on DVD-R's

[markw]

I have a odd problem that developed recently and I made two changes that made it hard to figure out. First, I switched from 1x ACCU DVD-R's to 8x ACCU DVD-R's as well as went from a Sony DRU-510A to a Sony DRU-530A.
I had settled on ACCU and have used that for the last year or two with rarely a problem but problems cropped up a couple months ago so I wonder if manufacturing changed. I blamed it on my drive at first. I thought it was the DRU-530A and happened to notice the problems then. Odd thing is it burned the 1x dvd's at 2x and I think a lot of them that were bad were these. The 8x dvd's burned at 4x. I got rid of the drive and went back to the DRU-510A but unfortunately have had it happen a couple times sense. Odd thing in this case it's the 4x dvd's. This drive will burn the 1x dvd's at 1x but the 4x dvd's although it says it is burning at 4x it truly burns at 2x (takes around 30 mins). From what I see about the DRU-530A I think that was a large part of my problem but still seem to have some problems on this 510A so wonder if it's media related also.
By blockiness what I mean is I have these odd blocks appear throughout a movie, often beginning, but sometimes during the movie and sometimes it's bad enough that the movie actually stops or won't play and it's like these multicolored garbled up boxes throughout the video.
I kind of suspect it's something that happens during finalizing. One thing I noticed, for some reason when Nero finishes burning some dvd's when I finish it it seems the finalizing takes far longer. These seem to be the problem DVD's most of the time. yet I have been able to take one of these dvd's and actually make another copy and the copy turns out fine telling me it's not the files on the DVD but something to do with finalizing or dvd quality.
I just want something that is going to last and I already wonder how many bad dvd's I have. I assumed the bad ones are the ones that are bad at the beginning but yet I have found problmes well into some other dvd's I never knew about. I want something that will last a long time also and won't be bad in 5 years. Any idea of another dvd-r brand I should look for? It seems this happens with either a cold or a warm dvd (I have heard temperature can make a difference).

Try different media such as Prodisc or the branded version of RiTek RiData.

I have this same problem and am using ritek 8x dvd-r discs. I have been playing around with which encoder I have been using. From Intervideo to Shrink to CCE. I use decrypter to get the files to the drive, then vob blanker to edit out some extras and chop credits, then one of the above to encode and write.

Does anyone else have and ideas on this?? I have used the same media always and I know that some come out fine and some are choppy, ususally toward the end.

Thanks!!
