I assumed you wanted to see the 540p upscale. Here are the comparisons. There are a few tiny differences between Video Enhancer and the Virtualdub plugin. I think this is due to the fact that I used RGB mode. This option is not available in Virtualdub (the default is YUV mode). Also I don't have a license for the VD version, so there onfortunately are watermarks in that one. If you want to see other comparisons, please let me know.
