Retrieving Favorites From Defunct YouTube App

I recently went through some old stuff and found my childhood iPod Touch, which had a burnt-out battery but still booted when I plugged it into a wall charger. I discovered the YouTube app no longer worked but instead told me it couldn't connect, and displayed "No Videos" under all the tabs on the bottom. This included the "Favorites" tab, even though I remembered making a lot of favorites when I used the YouTube app frequently, although I never made a YouTube account. Is there any way to retrieve the favorite videos? It's ostensibly a Gen 4 but apparently the 8gb gen 4 is considered a Gen 3 and cannot be upgraded past iOS 4.
