I ran short on time earlier while publishing and didn't realise until I came back that the CMS gobbled up all my line breaks. :eek:
Hopefully the formatting should be all sorted now, with the smileys stripped out.
That's actually a very good point and something I didn't think of at the time.
The FAT32 file system does indeed have a 4GB file size limit, so this will make it an issue storing HD files larger than this on its internal hard disk, unless they are broken up.
For external drives, I ran a quick test here and this will read NTFS from USB drives, so an option would be to use the internal hard disk for music, DVD folders and standard definition files and a USB HDD (e.g. a 500GB self-powered WD passport) formatted in NTFS for HD movies, such as those over 4GB in size.
