I bought one of those AV2HDMI converter boxes but STILL can't get mine to work (record tv/ota) - I have a new samsung smart tv and old panasonic vcr/dvd combo which I love love love....... but cannot record any of the over the air programs. I can watch old videos, prerecorded, but cannot record anything, and there are such great OTA programs that I never even knew existed as we had cable for many years (and don't miss it at ALL!). So how did your son manage to hook yours up? Thank you so much, Joanna
