<div><br></div><div>It *seems* to be related to the length of the episodes list as when scrolling down the left hand panel it is noticably faster for, say, films (split second scrolling) than children's programs (of which we have plenty, can take a good 3-4 seconds to populate the right hand panel).

I believe it has to do with a 0.27 change where the frontend now asks the backend to generate preview images at full resolution before scaling locally to the theme-specified resolution, instead of generating smaller preview images on the backend which are rescaled again on the frontend. I bet the difference in snappiness you observed is related to the preview image file size, which you can find by looking for the preview file in somewhere like ~/.mythtv/remotecache/ . You could probably confirm this by disabling preview images in your theme.</div>
<div class="gmail_extra"><br></div><div class="gmail_extra">To further confuse the issue, older recordings may be reusing older, smaller preview images on the backend and/or in the frontend remotecache directory, so for a truly fair comparison you'd want to remove *.png files from your Recordings storage group directories so that they get regenerated.</div>
