I’m a “happy” user of the WDTV Live since last week (and hopefully at least a bit longer) but while building up my DVD collection on my NAS, I ran into an issue with the caching of thumbnails.
First for explanation - here is the workflow that leads to the issue:
Place a thumbnail into the same folder as the ISO (I make ISOs from the DVDs) with the same name (".jpg" instead of “.iso”) at the size of 120x180.
Then start the WDTV Live and go through all the folders and ISOs to let the cache save the thumbnails onto the ISO icons.
Then rename all the JPGs to a “non”-media extension (I take “.jog”).
Now you have the thumbnails on the ISO icons and no JPG icons until the next “Hard Reset” (e.g. a disconnect from the power socket). If this happens, the cache is empty and you see the standard icons again.
At some point (I had around 100 ISOs saved) that “Caching” procedure froze the WDTV Live completely so only a “Hard Reset” brought it back to “live” . And it’s reproduceable (means - it happens now all the time so I had to say “Good Bye” to the useage of thumbnails) …
I guess it’s some kind of a memory issue … maybe I’m wrong.
I think the caching is no longer needed, if the “Don’t show thumbnails of JPGs in video folders on network shares.” issue is fixed, but you might have to look at it anyway.
