Rectangulars blocks on dvd-r

[victor010170]

Hi all,

I ripped dvd music (it has around 7 to 8 gb) with DVD shrink and burner it to DVD-R with either TMPGENC AUthor or with Vegas DVD. Watching the burned dvd, every time the singer moved, I see many rectangular blocks everywhere on the screen. But when the screen stand still, I do not see the blocks. What do you call that problem and how do you fix it? Your idea is appreciated. I also tried many diff types of media and still have the same issue with different speed such as 2x, and 4x.

I believe I've heard this referred to as "tiling".
When this was happening to me, it turned out to be anomolies introduced during the transcoding process. I was using CloneDVD2 at the time. It could be the quality of the transcoding process in the program you are using. You might try a different program and see if you get better results. The transcoding process is pretty machine intensive, and I did a few things to give it more power to work with. I generally perform the transcoding process from hard disc files to hard disc files (ie. NOT during the actual burning process). I keep my target location on a separate hard drive from my source files (I even keep the hard drives on separate channels). I have 1gb of memory for the program to play in. I give the program "high speed" in task manager. I eliminate as much stuff as possible from background running.
This can also happen if your burned media is not being read well due to burning problems. In that case, you need to consider the brand and type of media being used and whether it is compatible with your burner. You might also slow down the burn speed to something mid-range for your burner and media ratings. (ie. maybe try burning at 4x on 8x media with an 8x burner, for example).

I had the same problem using dvdshrink then nero 6 with an 8X Lite-On Drive. Everything was fine using Ritek 4X disks then I got some off brand media that was supposed to be 8X and running at 8X you could see strange patterns in the media and the playback would be all blocky.
The type of DVD player made a difference also. An expensive Panasonic player I bought a few years ago works a lot better than the cheap $30 Cyberhome type players that are around these days but you could still see it.

It sounds most like to high compression from the transcoding process. Unless you removed some of the structure (other languages, extras etc), you have recompressed this disk by almost 50%. This is a big ask under most circumstances. You would have been better off splitting the disk into 2 disks, or burning to a dual layer disk.
