Does Mint include HAL by default? If so, I'd guess that's the answer to why streaming of the Olympics works in Mint and not Ubuntu. The first time the NativeCache, AssetCache and APSPrivateData2 files are spawned in Mint, HAL is already present. In Ubuntu, those files already exist, so need to be deleted, and respawned, after HAL has been installed. My guess is that if you took a fresh Ubuntu installation, then installed HAL before doing anything with Flash, that we'd be able to stream the Olympics without any tweaking being necessary.
