Hi,
we are not aware of any such issue related to the size of the file. Is it possible the file name/folder or the label of the memory card contain characters that might cause a failure?
E.g. Percent, amp (&), none English characters etc. Try using purely English characters for file names/folders, devices have many bugs in these areas.
Thanks for the reply. Have tried with the filename "ts02e04.3GP" and I still get the "err" message.
The video plays fine using the phone's built in player. The file was generated by converting a .AVI using Super. Is there an incompatibility somewhere? As previously posted, the file is found without problem - it's just a problem when I click "add".
