Dailymotion-App: Is it possible to access the sync'ed videos somewhere else?
I know they're saved somewhere in the Cache (\mnt\sdcard\Android\data\com.dailymotion.dailymotion\cache\videos). If you clear the Cache, they're gone.
Is it possible to move them to somewhere else, e.g., on your sd card or even PC and watch them there.
Go to the cache, and find the file that you want to play. There will be 2 files with the same name, one will be only a few kb, the other will be the video (should be a few MB).
Long press on the file until you get the menu. Then select "open as", then "video", then select a video player.
I used the stock one that comes with the phone even though I have several others I thought I would try that first, and it worked first time (this was on a Galaxy S3).
If they play then copy them where you want, pc etc. You might need to rename the video files (adding the .mp4 file extension).
or
