I have recorded with the DH30000, and when done properly the results are the same as the HD1000. However, there are a few problems:
1) After a SVHS tape is inserted it is necessary change settings on the recorder to "DVHS" and "HS". It's easy to forget if you're in a hurry. I suppose the cassettes could be drilled to solve that problem.
2) Recording with the DST51 timer works, but both units have to be left on before the recording starts. After the recording is finished the DH30000 turns off but the DST51 stays on.
3) The DH30000 can't play back while connected to the DST51. It's necessary to switch to another input, unplug the iLink, or powerdown the DST51 before starting playback.
Other than that it's all a bowl of cherries. http://www.avsforum.com/ubb/smile.gif
