Attached picture This frame contains a picture directly related to the audio file. Image format is the MIME type and subtype [MIME] for the image. In the event that the MIME media type name is omitted, "image/" will be implied. The "image/png" [PNG] or "image/jpeg" [JFIF] picture format should be used when interoperability is wanted. Description is a short description of the picture, represented as a terminated text string. There may be several pictures attached to one file, each in their individual "APIC" frame, but only one with the same content descriptor. There may only be one picture with the picture type declared as picture type $01 and $02 respectively. There is the possibility to put only a link to the image file by using the 'MIME type' "-->" and having a complete URL [URL] instead of picture data. The use of linked files should however be used sparingly since there is the risk of separation of files.

So what your saying (to be absolutely sure) is that iTunes sets the limit of 256 chars in the comments field for media like music and video - specifically .mov. Which means at any time in the future Apple can lift that to allow for any length, like QT Pro does now? Thanks.
