WDLXTV is a souped up unofficial firmware for the Western Digital WDTV. It is based off the 1.03.01 firmware, but with many extra features. Similar to my dvdmod firmware, this is a permanent flash, just like an official upgrade. There is no Linux knowledge required to use WDLXTV.
I’ve finally found the time time make a new WDLXTV release, now based on WD TV firwmare 1.03.01. There have bee a lot of changes since the last published release, mostly background tweaks/bugfixes/enhancements.
