I bought a Motorola DCX3400-m pvr and have had it replaced once already because of its noise. The new one they replaced the old one with is louder. If it is left on for over 5 hours this thing can get so loud it distracdts from watching the porogram. Of course it is even worse if the TV is off as there is no drowning out the pvr sound. It is also loud when it records. Sounds like a hard drive sound that is constantly clicking and swishing, etc - the sound that all...
