Initial IDM-1731 Portable DVD Player with 7-Inch LCD
Very Good results for low price!
We have had a 5 inch model for a few years and it has the skipping problem every once in a while.  We decided we needed another unit due to family issues and wanted to keep in the Initial family. Prior to purchasing the the 7 inch, I contacted Initial customer support and mentioned all the issues that were reported here.  We were informed that they had made software modifications that eliminated the skipping and freezing.  We were advised to look for newer serial numbers.  We have had no issues with our new DVD player. We have found that the motor noise is helped by using Earplugs. All in all you just can't beat the price.
