How to do thumbnails?

Can anyone spell it out for a novice how to setup movie sheets. I tried moving my drives to Plex and it’s too resource heavy and bogs down my computer. So I’m sticking with the wdtv live. Any help is greatly appreciated. Thanks.

Subject says Thumbnails – content says Movie Sheets.

They’re two very different things.   

Which one are you asking about?

and also … which device do you own ?    (your post history has been in 3 different device forums)

WD TV Media Player

Sorry Im spastic. Not sure what other topics I was asking about when I first bout my WDTV live media player. I did, after last night, find the WDTVHubgen. I now have all the thumbnails etc viewable on my tv. The issue now is while the jpg is great on the computer, on the tv some (about half) are stuck at half loaded images. Any ideas? Right now I’m trying to uncompress the HD and see if it helps.
