I searched... but couldn't find an answer. I've noticed that the model numbers are similar. For example, HR20-100 and HR20-700, and then there's a HR21-100, and HR21-700. What do the 100 and 700 mean? Increased recording space? something else?
Welcome to the forums, edy! :welcome_s
The model numbers of current receivers are in 3 parts: 1) type: D, H, R, or HR; 2) family #: 10, 11, 15, 20, 21, 22, etc.; 3) -Manufacturer number like -100, -200, -300, -700.
D is a standard SD receiver only unit.
H is the HD model.
R is an SD DVR.
HR is the HD DVR models.
For the family, 1x are the first in the series, 2x are the second basically. The Current HD models are H or HR 2x: 20, 21, and 22. The H23 is the most recent non-DVR receiver.
Somewhere is a list of the Manufacturer numbers. -100 is Thomson, -700 is Pace. -600 is LG? -200 is Samsung.
