I don't think that would work. The new TiVo HD and S3 only have coax input for antenna and cable. There are no "open" input connections that allow for a simple signal feed to come in (meaning, already passed through your H20).
You are in a boat that is loading with more and more passengers. If you want to stay with DTV, you will have to go with the HR20. More info on dbstalk.com If you want to stay with TiVo, you will need to switch to cable or FiOS (if available), and get an S3 or HD. I did the latter.
There are rumors that DTV and TiVo might be working together again, but that might only be wishful thinking. Good luck.
