Multimedia, AV Geeks.com sent us for a review an external hard drive enclosure case, the "TVisto Series 3.5" Multimedia HDD Enclosure" (2.5" series also available). But this is not just another hard drive enclosure, but also a multimedia jukebox. And it's running uCLinux, an embedded version of Linux.

2.5":

# Playback Media Formats Video:
# MPEG-1 (AVI, MPG)
# MPEG-2 (AVI, VOB)
# MPEG-4 (AVI, DivX, DivX VOD, XviD)

# Audio:
# MP3

Isn't the difference a little bit too drastic? Why is format and FS support in the 2.5" version so poor? After all, 2.5" drives, while smaller, obviously have enough capacity to install all necessary software ;-) They could make a much cooler product with 2.5" (the same versatility plus a more compact package), but apparently didn't want that... What's the reason?

My guess is that because the 2.5" is physically much smaller, they had to use less memory and maybe even less video-related electronics. For example, if the firmware of the 3.5" runs on 4 MBs with two chips of 2 MBs each, they had to run on a single chip of 2 MBs on the 2.5" version. And that would mean only one thing: removal of drivers and code in order to fit on the 2 MBs ROM.
