Convert analog videos (VHS, VHS-C, Mini-DV) to digital files

I am struggling with converting my analog videos to digital format. I have read a lot of the articles on this forum and in my internet searches, but am not finding an easy way to convert without a lot of hassle. I have a USB encore electronics conversion device to bridge the VCR to my computer. I have PowerDirector for editing the files, but it is not performing well during the capture process. My old VHS tapes have breaks between sessions which PowerDirector translates as a copyright infringement and stops the capture. Is there a better way to convert my audio/video to digital without having to babysit the process? I would prefer not to have to watch every video during the process either. I can do that while I am editing them. I would appreciate as much help as possible.

I know there are quite a few conversion businesses which charge $5/tape or more to convert. What process do they use? I have well over 100 tapes to process, so the most efficient process would be awesome.
