Ever since I upgraded to Quicktime 7 Pro from 6.X, I seem to have lost the ability to select parts of some movie files with the selection indicators, the indicators simply do not appear when opening many of my files.

I always had selection indicators (left and right) that I could drag along the timeline in Quicktime versions earlier than version 7. The lack of indicators also make it impossible to select part of a file to edit (copy, clear, etc).

Are the files (a Beastie Boys, Sabotage video for example, downloaded off some p2p network) "protected" from editing? They are fairly old in many cases. If that's not the case, what else might it be? I have tried looking for an option that would affect this, but haven't been able to find anything of that nature yet.

Can anyone here shed some light on this perhaps?

I can think of two things: either you lost your Pro abilities when updating to QT7, or the files are MPEG-files.

I appear to retain my other Pro abilities at least. The files in question are MPEG-files though. Do I need to purchase the MPEG2-addon as well all of a sudden?

Again, this did work fine with just QT 6.x Pro. Nothing else was needed.

QT can't edit MPEG 1 or 2, and never could. In QT 4 it let you fake it (the edits were recorded, but the content was not actually changed). QT5 removed this half-assed solution (leaving a no-assed solution), and QT6 removed the vestigial interface elements that were confusing in 5. QT7 is the same as 6, except that now the selection markers fade in and out as a rollover action, which might confuse you on movies you actually can edit (ones that don't have MPEG 1 or 2 tracks).

And if you do need to edit MPEG file you can use MPEG Streamclip. (And the MPEG-2 plug-in from QT6 will work fine in QT7.)
