Hi people, Before I installed Perian, I used to get the 'Quicktime can not read, not in a format QT understands, blah blah' etc.. But I now have this again for an AVI. Any reasons why things would change. Looks exactly like the AVI files it usually reads, nothing is different, and does Perian also open WMV above Flip4Mac? Also today, the Flip4Mac came up for a WMV file, which I've not seen for ages. Is there a setting in Perian where it is the preference to use instead of Flip, I thought it had taken over all that stuff. Is there a control for Perian to decide what it opens, The 'open with' right click sometimes just says open with WMV player, which obviously only opens in QT via Flip?
