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.
American charges a $200 change or cancel fee for paid domestic flights (itâs as high as $450 for international travel). That fee is charged per flight! If you change or cancel a domestic round-trip flight, you will pay $200. If you change or cancel two one-way domestic flights you will pay $200 for each - or $400!
