Okay well it seems to matter what kind of file is inside the mkv container. I tried playing another video and it prompted me to buy the cinema plugin from archos. I went to try and buy it and I punched in my product number which starts with a 7 and it responded that my product number needs to start with a letter. grrrr.
I got yesterday my archos 70 IT. It is a nice device, slim, good quality build, except for a pretty sub-par camera. Shipped with android 2.1. However, I have run into a huge tethering problem and might have to return the device if I can't solve. I am not able to tether neither via bluetooth or Wifi. I have a T-Mobile Touch Pro 2. Of course, the wireless option gives me the problem of not being able to see the ad-hoc connection with the archos. However, I cannot use bluetooth either.
After I pair the device and I follow the whole BT tethering procedure I get on the archos an "unable to to connect by tethering" message. If I try to initiate the connection via the Touch Pro 2 using the function "Network Manager", and choosing to share an internet connection with the "A70S" (The archos 70) I get a message on the Touch Pro 2 saying that the device might be turned off or not support personal area network services.
I have used epc.tmobile.com as APN, but I have also tried wap.voicestream.com; t-mobile.com and others. Nothing seems to work. I am so frustrated. If I cannot fix it, I might have to return the Archos and go with a 3g enabled tablet. I planned to use the archos tablet for my long commute and without internet is not much helful. Any suggestion, advise?
