If anyone wants to suggest a future project that I may be able to put together, ideas welcome...e.g. 'B' above, remove the requirement of the PC, record/playback on a SD card as part of the unit. If you've got some older SD cards of 2GB or less hold on to them for this, I really don't want to mess with the e-FAT format, FAT16/FAT32 is OK, though the cards will not use any of the conventional formats...they'll be used simply as a glorified EEPROM - which is really all they are.
Using the same format as the PC-based version of 'B' above, a 1GB SD card will record over three hours of NBTV audio and video.
...however there is a caveat to this... using the proprietary SD card interface requires an expensive (for us lot) licence, the SPI interface is licence-free but of course slower.
FAT32 doesn't limit you to 2GB. It actually supports up to 2TB. Also, the SPI interface on an SD card is plenty fast enough for NBTV
