Called last night to get my installation set-up. The website stated that the newest feature of the 625 is name based recording. This is a must for me. I do not see this stated for the 510. I asked 2 different CSR if there were any differences between the 510 and the 625 besides being able to push programming to two sets. I was told that all other features and functionality are the same. Is this true? I am currently scheduled to have a 510 installed on one of my SD sets. Should I go with the 625 instead.
