The dvbreader.so in the satfinder plugin allows the preview of channels or services on a transponder to be seen. The dvbreader.so is an executable with permission set at 0755.

The dvbreader.so has been in TNAP satfinder for some time. I will take a guess and say that some previous attempts to fix Satfinder crashes AFTER the dvbreader.so was added has allowed the dvbreader.so to run while navigating the menus. This would explain the problems of sluggish operation in the receivers.

The Satfinder that is in the feeds now goes back probably at least a year and a half. The file size of this Satfinder is small in part because there are no efforts to fix crashes in it. You can add swap files (band aid on a bullet wound), install more memory, or whatever else you want to do. But if the dvbreader.so is allowed to run when it should not run, then you will have problems!
