Just want to clarify. I just did an upgrade for a friend. He has a Hughes SD-DVR40 unit. I used ptvupgrade 6.2 software. Now, I just want to clarify, does this support larger drives? I'm using 250 GB drive. As far as I understand I think it does, but want to make sure before I send it to him. I cannot test the unit since I do not have that model.
