I need to send a dropbox link of an xvid avi to my father and have him be able to open and play it on his iPad. I don't have an iPad so I can't test apps.
CineXplayer? AV Player HD? It's Playing app?
I need it to be as easy as humanly possible because it's my parents.
edit: I probably should've put this in the iPad Apps forum instead. My apologies.
1. You REALLY want to convert it to MP4 via HandBreak. It's far better to distribute videos in that format today as it's THE native video format of iOS.
2. Unfortunately, very few video player apps allow for direct (non-Web browser-based) Dropbox access.
3. many players have built-in Web browser and/or direct URL entering capabilities, as opposed to native Dropbox access. In general, GoodPlayer has the best HTTP streaming support - it was the winner of my recent Windows Media streaming roundup as well. It should play a DivX AVI as well. Could you provide a link to one of your existing online AVI files so that I can quickly test GoodPlayer and the other, HTTP streaming-capable players?
4, if you still need built-in native Dropbox support (it's in many respects better than HTTP access), let me know and I compile a list for you. (I've been working on an article series discussing everything multimedia on iOS so it'll be a comparatively easy task for me.)
5. Most apps rely on inter-app file sending, which, "thanks" to Apple's 200 Mbyte restriction, renders most long(er) videos unplayable if you download the videos from the official Dropbox client and try to transfer the file via "Open In".
