The wrappers can have some impact on the metadata. H.264 .mov and .mp4 also work in Flash. Adobe Engineers say that at some point there may be changes that involve the metadata. Personally I find H.264 .mp4 safer given that such file can also be used in HTML5 when the time comes.
In Squeeze just look to see if they have any Flash 9 presets. H.264 .f4v is often referred to as Flash 9.
We actually have had a tin of F4V topics already discussed in Craig's responses to them, many of them I've posted, so for more F4V info that may or may not have been posted, check out a search on this forum under "F4V". Lots of links and explanations all over.
