There is no "easy" way to bridge synology to Tivo. I run pytivo on my Synology DS111. The setup isn't really that bad. The most trouble I had was getting it to start up on the synology at boot.
If you have any devices that support DLNA (TV or bluray or roku or similar), then you can probably use the synology media streamer or Plex or Serviio to stream content. I have used Plex and Serviio to my panasonic TV and a roku. You cannot transcode video with your synology (nor mine). They just don't have the power needed for it.
