Dear Stefan, Thanks for your reply. I think I didn't explain my question very well.
If x-content/audio-dvd, x-content/video-bluray, x-content/video-hddvd etc. are valid MIME types, detected by the presence of certain files or directory structures, should there also be a MIME type for AVCHD, indicated by the presence of a path PRIVATE/AVCHD/BDMV/STREAM? But perhaps there is a good reason why this is not the case? Thanks.
