Just regarding the HD playback on the phone.

1. Youtube sucks even in HQ - am I doing something wrong? Amendment in settings?

2. Noticed it will not play any avi. file formats - again - my mistake or do they need converting first?

3. I have a 720p HD film in MP4 format - however it will not play on my phone. I just get the broken video icon on screen when I attempt to start it. I noticed the Source Code trailer already on the phone is in the MP4 format so unsure what I have done wrong
