yes, but it's not quite as good IMHO. i've used it. it comes on my cooked ROM. for one thing, the youtube app doesn't allow you to login to your account to load up your favorites. if you do it the other way, you go vie PIE (Pocket IE), login to your account, and all your favorites are available to you. TCPMP is faster during playback. my phone actually can't keep up with the audio/video properly using the youtube player... it becomes desynced. TCPMP also has a lot more options, allowing you to zoom the video differently, rotate to portrait/canvas modes the way you want, and also a built in EQ. it'll also playback in stereo. i have no idea if the youtube player even does that. doing it my way, PIE will also allow you to actually save the FLV file to memory instead of just streaming it.
