Hi ChickenMan, I'm the author of 1Click DVD Copy. I can assure you that the transcoder is "tried and tested" - it's been around longer than most transcoders. There are over a million users now and we haven't changed much in the transcoding lately. The problem described by AMBAKER (above) appears to be related to burning since he mentioned that the files produced by 1Click were working with CloneDVD.
1Click DVD Copy uses VSO's burning engine (CopyToDVD) to burn. This engine will attempt to burn using two different techniques - SAO and DAO. Depending on which one is being used (settings can change this), the resulting DVD may not be playback compatible with his DVD player.
If someone is having a burning problem, the shortest path to resolution is to send the "c2cd.log" file to our tech support and they'll analyize it and offer a solution.
