I have been using it for a while and has been quite satisfied with it. I use Seagate 1 tb drive to playback files from.
Nowdays i see that USB status LED keeps on blinking on WDTV forver when my drive is attached to WDTV. I do have around 146GB of free space on drive.
And either due to that or maybe another reason but sometimes it takes considerable more time for WDTV to beging playing back a file than before. Not with all filed but with some files.
Firmware versio i have is 1.05.04_B
