Hello forum, long time no see. We moved recently. I left the dish up because I didn't have time to get a ladder. I had the old manhattan 1100c receiver. It was old. I still have it btw. The facing on the remote was worned off. it was time to get another system. So, I ordered the hdvr 3500. So far I am impressed. I have one problem though: I can't figure out how to record. i was listening to something I wanted to record, but nothing happened. I got out the fine manual and it said something about the receiver has built in memory, but that i could also add a mobile hard drive or a flash drive. Although flash drives were mentioned it said something about that type of memory is not preferred. Can someone help me out with this?
