All I can say is that I purchased the EH50 two months ago and love it.
I have made countless recordings to the HDD and have burned about 16 DVD-Rs.
My use of the EH50 is to record from my Digital Cable to the HDD for time-shift viewing as well as archiving to DVD-R. I also have used it to record some very important VHS material onto the HDD and then dub to DVD-R.
There are many threads on the EH50 here which should give you all the info you need.
