Upgraded firmware for Classic (to 1.0.34). Result – no picture. I wonder of someone show me how to ‘reverse’ a firmware upgrade.  The other evening I installed a new version of slingplayer, which then instructed me to upgrade the firmware. The result is no picture and no sound.  I did a ‘factory re-set,’ but it did not solve the problem. All the channels are there – even after I do a re-scan (with the new firmware in place), but no sound or picture.  The streaming speed I now get is from 5 to 25 kb/s.The new slingplayer version I installed is 1.5.1.335, and the new firmware version is 1.0.34, dated 12/31/2007. I would like to revert to what I originally had. Any help would be greatly appreciated.
