My card worked fine for about a week and a half and then I suddenly started to experience the static issue when changing channels. At that point, the only things I had done differently was start running lirc with irevent, and I had put the side on my case. Once I determined that it wasn't LIRC causing the problem, I took the side back off my case and now it happens a lot less. At this point, I am not guaranteeing that it is a heat issue, but it is kinda conspicuous. I am going to do some more testing to see if it is more prevalent when the case cannot breath as well.
As far as the rattling, mine does that too. Initially, i thought it might be detrimental to the card, but it works perfectly fine using the stock Hauppauge driver in XP on the same computer.
I am still having signal problems on the first tuner like some others. Are you guys also having problems with the first tuner being more staticy than the second tuner as well? I am trying to narrow down if this is a universal problem or if it is affecting only some people with the Samsung tuners.
These Sumsung tuners are so wacky.

The main differences between our setups are the tuner card (mine is a PVR500 with Samsung tuners), computer (mine is a Dell PowerEdge 2450), and distro (I'm using FC4).
Otherwise everything appears identical.
I'm going to RMA this card as there is a rattle in what I believe to be the signal splitter box on the card itself but I don't have much faith in that fixing the problem as this only ever appears to happen on the second tuner. --- Ben Kohn www.benkohn.com

This is my first attempt to setup a mythtv box. I am using a PVR500 card (Philips Tunner) on a nforce2 motherboard running a Athlon XP 1700 processor.
The OS is suse 10 and I followed the howto on the http://ivtvdriver.org website. The very first time I tried to test the card it worked fine. Then I tried to change channels and that's when I sound went bad. By bad I mean that the actual audio goes very low and there is a lot of static and chite noise. After reading a lot thry google I think I have the little sound problem. If I keep on changing the channel it recovers for some random channels and again goes bad when I change channels. Also repeted setting of the audio inputs to the tunner with ivtvctl helps some times.
I tried from version 4.0 to the SVN version of the 0.4branch. All the versions have the same problem.
The video is fine in all the versions.
My question is wether this is a driver issue or a hardware problem? If it is a driver problem, can anybody tell me how to fix it or what I can do to help the developers debug it.
