I have both the Drs7000n and the Drc7005n. I have not tried to upload pictures or music to either unit. I am using both as a VCR subsitutes. I use local cable with/o at setup box.
The DRC70005n is slightly better. It has 4 recording modes High, normal ,basic, and low quality. In low quality it gives an acceptable picture
with the benefit of giving me 64hours of recording time.
The Drs7000n gives you 3 recording modes and only allows for 40 hours
of recording time in basic quality. Yet the picture is similar to the low quality
in the Drc70005n.
The Drc7005n does not seem to require the Svideo cable connection to deliver the Tv input. Drs7000n seems to require it.
I have had no technical problems with either unit .
The Guide plus feature is the weak link. It does not cover all the cable channels my cable provider Alephia provides. Specifically it does not list the cartoon channel. IT is hard to use as opposed to programing the unit manually. Yet you must use it in order to keep the clocks in both units on time.
Drc70005n uses the GuidePlus better. After a power outage it automaticly syncs the its clock to the correct time. With the Drs7000n you must reset the Guide Plus system manually.
Finally the DRC70005n seems to be upgradable. While the DRS7000n is not.
I have upgraded my DRC7005n, with an 80 gig harddrive made by Seagate.
I now get 128 hours of recording in low quality mode.
