After reading countless posts, please verify my understanding is correct re Linksheets on the SMP device.
Linksheets are intended to be stored on the device’s internal storage. In the case of SMP, it is limited to only 30MB.
Therefore in order to use Linksheets to display movie/tv info, you need to use a custom firmware for the SMP. This firmware allows linksheets to instead be stored on devices (NAS, shares, USB) that would have enough capacity to store all the movie linksheets.
When your firmware is modified you can then use the available themes out there (Coco, Goodby, simplicity) on your SMP.
Linksheets are generated using the Thumbgen profiles generally provided by the SMP themes themselves.
A linksheet is an image (.jpg) that is generated by Thumbgen for each movie (or TV show).
The primary benefit of Linksheets (instead of the old moviesheet, with iso_sheet & xml) is faster loading.
Displaying by Linksheets no longer requires the .xml files. It’s only 1 image file to 1 movie file requirement.
Am I close?
