I have had a 722k about 4 months (new to Dish), the only time it crashes (<= 10 times) is when attempting a search (99% of searches do not crash), # of searches does not seem to matter (using history) but it has ALWAYS been when attempting a search. Press search, no reaction, then reset, then all is well until..... Is this just my 722k? Also, since adding an external usb HDD, (and I have not had it connected for weeks now) it gets the slow down issue (slow epg, slow everything but records fine) effectively daily! If I do a reset daily it does not seem to get the slow downs, or ONLY late at night. Is it just my 722k or did I get a 'bad' one or do many do this? Thanks!
