Hi, I use DVD2One since 1.40 version with 'constant ration' and everything worked fine, but, with the new 1.50 version a new 'Compression Mode' was added, the 'Selective Ratio' with 3 options 'low' 'medium' and 'high'. The question is: which compression mode gives better results for movie only (not full disc)? 1. Variable Ratio ? 2. Constant Ratio ? 3. Selective Ratio (low, medium, high) ?
