It's hard to help when you post a general statement that you cant record and you provide no info.
Yes you said you didn't understand one of my questions but you didn't answer any.
I could have asked more but I asked those to narrow it down.
I'm not here to give you a hard time ,here to help
Do you shut unit off after setting up recording?
Are you using one button pvr?
Recording from guide?
Manual?
