PSPTube 01/06/2008 has been released.
I don't see any release notes or mention of it so maybe we're not supposed to know yet. But I changed the date on the other download link to today's date and voila!
I'm using it right now.
From what I can tell...it has a frame counter and how many seconds into the movie you are on the bottom right hand screen.
Also, new selections for searching: NicoNico, Onsen, and Dailymotion.
Still don't see any controls for rewinding or fast forwarding =/.
Let me know what you guys find.
