Some legacy systems (vendor-abandoned, long broken and due for serious upgrades for years)
can indeed have playback issues -- if there are subtitles involved and if a couple of
stars in the immediate vicinity align.
Apart from that long one-reelers are fine on playback systems.
That said and as you mention: There are significant and compelling reasons to _not_ go for
one-reelers in authoring and packaging. E.g. a lab is slow when it can test only after all
200.000 frames are done instead of the first reel of 30.000. Everything you do in
authoring and packaging you want to be able to do in batches.

Hello everyone,
I have created four 24- to 32-minute long DCP packages for a friend and hobby filmmaker
who is going to screen them at a local movie festival. Now, I've heard back from their
technical department that the DCPs I made using DVD-o-matic are single-reel and that
"might cause problems", whatever that means.
As far as I understand it, there is a convention to limit reels to somewhere around 22
minutes (e.g. typical old "analog" reel size) to minimize problems in transfer
and handling and to keep the sizes of the files in the DCPs reasonable. But I wouldn't
have thought that a 32-minute single-reel DCP might be problematic. Can anyone enlighten
me on the subject? I'm no projectionist or TMS technician (I'm helping my friend
because I have maginally more hobby experience creating DCPs than him), so there's a
huge question mark hanging above my head. :-)
Furthermore, is there any possibility to create multi-reel DCP packages via DCP-o-matic,
or to convert the single-reel packages into multi-reel using open-source tools?
Thanks for any help in this matter
Kasi Mir
