If the app iTube does not cache videos anymore, uninstall it completely and reinstall it.
It may be due to an outdated app. Make sure that the Youtube app is up to date. You should also make sure that the internet connection is working.
No, there is not youtube app on the sharp tv.
You cannot update a 4th generation iPod Touch to iOS 5 anymore because Apple will force you to update to iOS 6. The worst that will happen is you will lose YouTube, but there are other YouTube apps on the App Store like Jasmine and Google's YouTube app.
look it up on youtube
Unfortunately, Nanovor has been shut down and no longer is for the PC. You can get it though on mobile devices as an app.
iOS 6 removes the YouTube app from Apple, but you can still watch YouTube videos in the Safari browser via the YouTube plug-in (without need of Flash). If that is too slow, you can get the YouTube app from Google on the App Store. If that app's interface is too buggy, my personal favorite is an app called Jasmine. It too plays YouTube videos, but has a great interface similar to the old iOS YouTube app.
If Installous 5 is no longer working on your phone anymore, you may want to double the version of the app. Updates are launched frequently which can help fix any bugs that may be clogging the system.
No. The YouTube app comes with the iPad standard.
yes
You need to go to the YouTube app. Sign into your YouTube account via the app. Go to More (I think) and upload it. Hope this helped!
No. There is no app for that
