I am running Mac OS 10.9.3, Toast 10.0.9, TiVo Transfer 2.0 on a MacBook Pro. I have a 2 hour show that I cannot get to burn more than 1 hour, or less. I have direct connect with Ethernet to the router. I have tried several different shows with similar results. I realize I may need a DVD double layer. It does not give me the option of changing to double layer. I have a USB Apple Floppy drive that I have burned Double Layer before. When I play the show with Toast Video Player, it shows only 1 hour, from TiVo transfer, but that shows 2:04 time, 5.1GB. The TiVo DVR on TiVo Transfer shows 2:04 time and 10.7GB. I assume that there is a translation from the DVR to TiVo Library Recordings. Any ideas or hints would be appreciated. Thanks.
