My experience of Kiss players is not good, they do seem to degrade over time.
I've had 2 now, both failed within a year.
My last one, a DP-1000 lasted about 6 months, then the front controls stopped working but the remote worked, the player would always crash if you paused a divx for more than a few seconds, the VFD display went totally apes**t and now finally, the player will no longer read DVDRs with Divx files on them although standard DVDs and DVDR movies work ok.
No upgrade of firmware dealt with the Divx crashing. It will be replaced with a Media PC once HCDP enabled gfx cards are plentily available.
