A DTC-100, modified by 169time, has a IEEE1394 interface. It will allow you to view/listen to DVHS tapes made by a Panasonic PV-HD1000 DVHS VCR. It will also allow you to record OTA DTV programs on the Panasonic.
If current plans work out, it might be upgradeable to allow you to record/playback DirecTV HDTV. This is still in progress and may or may not ever be available. Time will tell.
They have had serious problems in the past fulfilling previous orders. This issue dates back over a year. Some AVS members have accused 169time of fraudulent business practices. Recently, respected AVS member Richard Adams has accepted responsibility and has started to rebuild the 169time name and reputation. Another AVS member, h20fun (Dave), is the prime contact that other members have used to work with Richard and get 169time to live up to their commitments. A number of members have posted that Richard has shipped their product and has assisted them with HDTV recording using the 169time modification.
Do a search for 169time and AVS members Richard Adams & h20fun for a lot more information.
