Neither the DTC-100 nor the Dish 6000 will work, as is. So far the only U.S. HDTV product that has been confirmed to work with the JVC HM-DH30000 is the Panasonic TU-DST50/51 OTA HDTV tuners.
16x9Time will soon be modifying the DTC-100 to add Firewire ports. There is an option to make these Firewire ports able to record and play back from the Panasonic PV-HD1000 D-VHS deck. Theoretically the 169Time mod. should also recognize the JVC VCR. But no one has confirmed this.
You can still record OTA signals with the JVC using the TU-DST50/51. Also, if you have a Dish 5000 and modulator, you can record SHO and HBO.
