Sometimes yes, other times no! I have 2 of the HR24s stacked on my AV rack which are for my sole use. I delete a show after I watch it and get the slow refresh and it doesn't seem to matter whether the show I'm deleting is on the one I'm controlling or across the network or not. Of course, when I do some mass deletings I fully expect it to take a bit of time, but not for a single show deletion regardless of location. For info, both units have more than 50% free almost all the time.
