The only thing I know about Aimersoft (as well as other brands used by Wondershare) is that they send spam. So their "soft" is automatically out of my list of recommended programs. I don't support spammers, so I don't want to encourage them to produce more trash content.

Anyway, any lossy DRM removal software works like screen video capture program when re-recording videos. So you can use any screen recorder that supports MPEG-2 video codec. Then it would be a good idea to author DVD-Video from MPG videos files without any quality loss. Note that MPEG-2 video files need to be DVD compliant to avoid recompression:
- Video 720x576 (PAL) or 720x480 (NTSC)
- Audio MP2 or AC3, 48000Hz
