Morning all, Firstly thanks in advance for any assistance or replies I receive to the questions and issues I am facing. Firstly I have the following Seagate 500GB Wireless Hard Drive (White not black) http://www.argos.co.uk/static/Product/partNumber/3552005.htm I have set this up on my iphone using the app and also linked it to my wifi. I have a number of films on it and am streaming the movies using my phone as a remote to a google chromecast but this is where I encounter issues. The chromecast or Seagate app are saying that AVI formats are not valid or streamable. I can only stream the ones which are MP4. Do anyone know a way around this without converting all the films from avi to MP4 and if not then can anyone recommend a free converter software that does not take all day literally to do a couple of films as I am using a free avc converter software and it took from 11am until 8pm yesterday to convert just 3 films :-( Thanks.
