Try holding the Samsung remote buttons down longer, and about 2 inches away. I just got the T165 and I had to do the cursor commands twice. But, it works fine! I have no problems using the TSU-3000 with the T165. With no real template for a HDTV receiver I had to learn alot of codes, but it went fine.I have learned alot of codes with no problems. I have never owned a Pronto before, so I am not trying to convert files if that makes a difference. Can these files be uploaded with the IR commands to the website? Trying to custom design the T165 pages took longer. Tell me if getting you a file with the codes in it would help.
