Transferring files to the i2 was quite a positive experience and an average 700MB AVI file was copied across in about two to three minutes. The manual quotes a transfer speed of 18MB/sec, much slower than the theoretical maximum of 60MB/sec of USB 2.0. This limitation is like to be partly due to the USB to IDE interface on the player and partly down to the fairly slow hard drive. However, this is not really an issue as the i2 isn’t any slower than other PMP devices when it comes to transferring files. File transfer is done by simply dragging and dropping whatever you want into a folder on the i2.
I transferred various video content to the i2 to see how well it coped with differently encoded video. All but one of the video files played back flawlessly, the one that didn’t play does seem to be a particularly difficult file, and I haven’t managed to get it to play on any portable device – so the i2 can’t be criticised for that. The screen is generally good enough for watching video, but as everything I played on the i2 seemed to be interlaced it’s not up there with say a portable DVD player or the Sony PSP in terms of quality. Connecting the i2 to a TV worked well and after having set the correct TV system the picture quality was pretty good, considering the limitations of the outputs.
Upgrading the firmware was something of a pain, as the software is in Korean and for some reason it didn’t want to know when I tried to upgrade to the latest version. Luckily you can just replace the files on the i2 and then copy the firmware file across on its own which auto updates the player the next time you switch it on. At least there seems to be plenty of firmware updates on the manufacturer’s website, which in a way is a good sign that the device is being supported.
