It now looks like we will be away in the 2 weeks when DSO happens in our area. I noticed on the humaxdirect website a claim that the HD never needs re-tuning. I couldn't spot an equivalent claim for the HDR. So here are the questions: Does the HDR need re-tuning for the DSO? If the answer to the above is yes, then is it possible to initiate a re-tuning remotely via the web or telnet? I don't mind getting my hands dirty if the interface to a re-scan exists and it's just a question of writing some code to call it.
