Hi, I'm attempting to do the same thing in python and getting the "400 Bad Request" response too. Can you provide additional info on how you got this to work and confirm that POST rather than GET was the solution? I'm new to python and post/get methods, so the issue may be there, but can you confirm that sending the CMDUrl string with '&cmd=delete' or '&cmd=delete&rerecord=1' (per https://info.hdhomerun.com/info/dvr_api ... recordings
) is all that is required? For example, if the CMDUrl for an episode is "http://10.0.0.1:80/recorded/cmd?id=ca94db7c
", then I just need to POST "http://10.0.0.1:80/recorded/cmd?id=ca94db7c&cmd=delete
