Advertisements Hi all: I've recently purchased a TIVOHD and am having a few problems. I'm guessing some of you may have had these and can help. Let me start: My previous setup was a SONY SXRD 60 inch TV to which I ran an antenna to directly. Then I ran and audio via optical to the Pioneer Elite 74txvi receiver - everything worked great - outstanding picture, perfect sound. I then bought the TIVOHD, hooked into the Elite 74txvi via HDMI and I've had nothing but problems. Audio - a noticable hum during programming - both recorded and live. When I hit "mute" on the receiver, the hum goes away. Video: The picture from the HDTIVO (which uses it's own tuner) is very soft and not nearly as sharp as when I ran the antenna cable directly into the TV. Keep in mind that I'm not using cable or satellite - it is just plain 'ole digital antenna. I purchased the TIVO to be able to record all the HD shows on network TV. Here is what I've tried so far: 1. Replaced the HDMI cable with an expensive monster one. Didn't seem to make much difference from the "cheap" Dynex from Best Buy. 2. I've played around with the various video output resolutions on the TIVOHD to now avail. I had an UNBELIEVABLE picture and perfect sound when I connected the antenna coax directly to the TV. Now, frankly, it hardly looks HDTV like using the TIVO. Are these HDTIVO's bad? Do I just have a "bad" one? Has anyone else had these type of issues? Could it be that the Pioneer Elite 74xtvi is a bad unit and is prone to these issues? Any insight from anyone would be greatly appreciated!
