New to ATV and ATVFLASH - few questions please

Hi (new to forum)

I have been looking at options including ATV and WDTV live however the ATVflash looks like it may solve my issues with ATV. But I have some questions:-

  1. What is the full list of video file types you can use with ATVFLASH, cant find on website.
  2. Does youtube work ok allowing you to log on AND access your favorites…do you have to use boxee or can you do with YOUTUBE on ATV menu (I read you cant)
  3. How long does ATV take from switch on to use it.
  4. Whats it like with an external HDD in terms of speed and quality when you have all your DVD’s saved on the ext HDD.
  5. Does BBC IPLAYER work correctly?
  6. Is it wireless n?
  7. Any drawbacks against my other options which is WDTV live or Acer revo
