Is there a limit on MP4 file size

[Bob2nd]

I am using Nero recode to create mp4 files (using IPod profile).
If the bit rate is set at 2.5Mbps and the movie is over 2 hours the mp4 file created will play on a PC but not on the OSD.
If the bit rate is set at 2.0Mbps for the same movie it plays on both the PC and OSD.

The only difference in the resulting file is size (ie. 2.5Mbps yields a file > 2GB and the 2.0Mbps yeilds a file < 2GB)

The file is stored on a networked NTFS drive accessable from the PC and OSD.

I think there is a 2Gb file size limit for SAMBA shares, so if you have the file on an external HDD connected to the OSD directly (not through a network), it should play. Can someone confirm?

I'm not sure about that FJ. I looks like cifs was designed to support large file sizes (>2GB). I'm not sure but people suggest using the "-o lfs" option when mounting the share. Bob2nd, could you try telnetting into the OSD & manually mount your PC's network share there? Just to test it out?

If you try FJ's suggestion, make sure the external HDD is not FAT32, since it has a 2GB limit (as I'm sure you know). The OSD can write to ext2 & ext3 formatted drives.

I does sound like the >2GB file is being truncated, doesn't it? PC's are forgiving when playing such files. If you use VLC have a look at it's error messages as you play the >2GB file.
