I download UM DVD Ripper from their official website and rip several movies. This tool is excellent, easy-to-use and having good vision effect. But I dislike the logo in the screen when I play the movies I've already ripped. Is there any way to get the watermark away?
Watermarks are really frustrating. You might have downloaded the free version. You need to get the registered version in which it is possible to remove watermarks.
Not all of the free version has watermark, I used Leawo free DVD to MP4 Converter before, it's totally clean.
