Reading and writing problems

When writing, and reading of DVD-RW Verbatim occurred considerable difficulties. When writing with Samsung DVD Recorder DVD-HR 775 A picture jumps occurred while DVDs of other manufacturers could be described easily. The DVDs were not read by a Samsung DVD drive in my desktop PC; the same problem also occurred in my notebook the Samsung DVD drive. All drives are compatible with the format DVD-RW. I therefore assume that I purchased DVD-RW Verbatim not harmonize with Samsung drives. No problems, however, occurred in a Sharp DVD recorder. However, in my view volumes that can only be used on certain drives, are unsuitable, I strongly recommend the purchase of this product.
