I upgraded to Mavericks on release by Apple and now find that my TiVo tranfer is almost completly stuffed. At the very least an already cumbersome process is twice as slow as previously and sometimes just falls in a heap/hangs and does not complete the transfer. The TiVo transfer capability was my main reason for buying this software which worked under previous versions of the Mac OS but now needs an upgrade. The problems happen on a 2013 macbook pro retina and on an iMac. Would love some help. Contacted TiVo whose suggestions to get around the problem did not work - they acknowledge that their suggested solution does not always work. Any thoughts?
