Have been unable to copy HBO & other premium movie channels to my PanasonicDMR EH75V. I have been reading discussions re the Dimax Grex. Most of the comments said the customer service was poor or never replied. I wrote customer service a long email, describing my problems in details and asking if the Grex could solve them. Then ,afraid I wouldn't hear from them, I just went ahead and ordered it since I want to fix this recording problem. I was surprised when I heard from them the next morning and they told me this should solve my problem and to be sure I asked for the latest version Grex 651 when I ordered. I wrote back and said I placed the order already. They wrote back an hour later asking what name the order placed under. I replied. This morning got an email that I got the newest model and it was shipped via air and a tracking #. I did the tracking and the only problem was the site was in Israeli language. I saw a blank and put in the # and it gave today's shipping date. Anyway, their customer service is excellent and I'll let you know how it works when I get it. When I had called my cable company originally, they said they knew nothing re copying blocked on these channels.
