What file system are you using on the disk. If it’s ext2 or ext3

If so install xfs packages, and convert your video work space, and

I use ext3 and have many files >2 GB, so can't be a limitation of ext3...
Nor is it a limitation of ext2--unless, of course, you're still using a
Linux 2.2 system and associated (ancient) libraries... (See

So, if you followed the ext2/ext3 recommendations from the MythTV
documentation ( http://mythtv.org/docs/mythtv-HOWTO-23.html#ss23.2 ) and
used "-T largefile4" on any recording partition of reasonable size
(which would have allowed mke2fs to choose 4KiB blocks), you can have a
2TiB file--assuming you've got the drives to allow it...
