I have had this app for a while now and when I play high def video it seems to play 30 secs then buffer, 30 secs then buffer.. I just downloaded the most recent version and it still sucks.. I read the lengthy article/tip on tweaking the wireless router.. This isn't gonna happen.. If I have to redo my router settings in order to get this app working correctly then it isn't worth installing. It works great on low quality but why own a HD TV if you just gonna watch the same ole 480p. So not worth the trouble..
