This was a bad buy. It did not work properly and I am very disappointed with it. Not good customer service. After hours of troubleshooting we realized the unit needs to be returned for replacement. Hopefully it will end up working properly.

Ex Output:
Bad review


Ex Input:
I recently purchased an eVo mini, and it appeared to connect flawlessly with my existing cable system which provides both cablecard & standard definition broadcasts. Using the DVR provided by TIVO - The TiVo, however, will not receive a signal using their broadcast guide. It appears that Tivo's box is just supposed to provide the live channels offered through their satellite service without any effort from one's part. It's definitely too easy.

Ex Output:
Good Review
