[QUOTE="fforde, post: 550017, member: 52082"] [SIZE="4"]The Problem[/SIZE] Okay, so here is the issue. MediaPortal has for some time now cached all PNG image files in the thumbs folder. The purpose of this is to cache TV logos, but because the caching process is not specific a whole bunch of stuff could be cached that isn't supposed to be. This has not been a problem in the past because up until Moving Pictures 1.0 Beta 2 cover art was saved as a JPG. We changed this to a PNG in Beta 2 so we are suddenly affected by this bug. The reason this seemed to be occuring with some skins and not others is because the issue occurs when building the skin cache. Meaning if you install a new skin or switch to one you have never used before (like Blue3Wide), caching is triggered and you experience the bug. Continuing to use a skin you already had installed and had used in the past will cause no problems because the skin cache has already been created. [SIZE="4"]The Temporary Solution[/SIZE] You can tell MediaPortal to not cache items in your thumbs folder with a special configuration setting in mediaportal.xml. [LIST=1] [*]On the Start Menu under the MediaPortal program group is a link called "User Files". Click this. [*]In the folder that has now opened, look for the file "MediaPortal.xml". Right click this file and open it with your favorite text editor (Notepad for example). [*]Search the file for the following text: [FONT="Courier New"]<section name="debug">[/FONT] [*] Directly [i]underneath[/i] the section text you just searched for, add the following line: [FONT="Courier New"]<entry name="packLogoGfx">no</entry>[/FONT] The debug section should now look something like this: [code] <section name="debug"> <entry name="packLogoGfx">no</entry> <entry name="useS3Hack">no</entry> </section>[/code] [*]Save the file and try launching MediaPortal, it should start up fine now. [/LIST] Please note that using this work around will also prevent [i]some[/i] logos from being cached which may result in some flickering or minor performance issues in the official TV component of MediaPortal. As far as I know [I]only[/I] logos for the official MediaPortal TV component will be affected. And these logos will still be displayed properly, they simply will not be preloaded into memory ahead of time. [SIZE="4"]The Long Term Solution[/SIZE] With the next release of Moving Pictures we will change the file extension used for downloaded artwork so that MediaPortal no longer caches these images. We plan to release Moving Pictures 1.0 RC within a few days. [/QUOTE]
