You may need software that will rip the files to something like MP4 format. DVDCatalyst, a forum sponsor, has a great program that has optimized settings for many tablets. It's $10 US but worth every penny.
In the first place, make sure if the recorded TV shows are protected. Use free tool mediainfo to check file information.
If not, convert the recordings (mostly .dvr format) to MP4 and copy the MP4 files to your Android slab. Otherwise the shows can't be converted and played on Android.
