Hej,
VLC reads them fine at least, but sure for editing it seems a pain in the [admin: avoid swearing please].
We should just send a ton of mails to canon together because this is so stupid to use that sucky format (I hate Quicktime, I removed that virus long time ago from my computer and will never have it on again).
If you have to convert every file, it sucks as well.
Oh and with the mass mail, write one sentence or two about old powershot A style being dead. :/ I need a new one with the IS to replace my old A540 when I won't bother taking my super zoom with me. A590 was perfect, except for the 20i/s video. Damned.
