You can see list of supported video formats, when open the drop-down list of file types near the bottom of the Insert Movie and Sound dialog box. I have no problem with playing video of different formats in my LibreOffice Impress. I suggest you install last codec pack, for instance K-Lite Codec Pack. edit delete.
The rules are the same for paid tickets. American Airlines Canceling an award ticket costs $150 for the first award, and $25 for each additional award reinstated at the same time for the same account. Thereâs no fee to change an award ticket, so long as the origin and destination remain the same.
Close-in booking fees: Most U.S. airlines impose fees for booking awards within a certain window of time (usually 21 days out). American, United and US Airways will charge $75 per ticket to do so, though they will waive this fee for some elite-status fliers. Consider: Alaska Airlines, British and Delta Air Lines do not impose close-in booking fees, so by booking through one mileage program instead of another, you can end up saving. Change and cancellation/redeposit fees: When you change an airline ticket, you probably will pay a fee.
