I notice in some review , other be have issue with hd resolution , when run hdmus out from the Tivo hd -lrb- series 3 -rrb- to the Yamaha yht-s400 system , and pass trough the video via hdmus from the Yamaha to the tv . -lrb- the resolution be be bump down to 720 from 1080us -rrb- . since there be a lightning deal for this item at only $ 250 , I take a chance , think I could get thing to work . I hook it up , run hdmus from the Tivo to the tv directly , and then run separate audio from the Tivo 's digital out -lrb- toslink -rrb- , to the yht-s400 . on the plus side , this solve all video hd issue , and the 3:1 sound , sound great . on the negative side , when change channel on the tivo , as the receiver figure out each channel digital audio signal , it send a second-long static buzz through the speaker . this get annoying quickly when you be flip through the channel and get this jarring sound every time you switch . I have run this Tivo and other series-3 hd tivo through other 5.1 receiver , and never have this problem . so I be send the Yamaha back .
