<div class="im">This sounds almost exactly like the reboot issue I've been having. I'm<br>
using a AMD processor, but the motherboard is VIA chipsets. I am running<br>
CentOS. The kernel reports itself as 2.6.18, but there a lot of<br>
backporting in it.<br>
<br>
I am going to start compiling vanilla kernels and see if I can find one<br>
where the PVR-500 is stable. I'm starting with 2.6.25 and working backwards.<br>
<br>
I am not willing to bet on my success. My issue could easily be a<br>
hardware problem. My gut says it's not, though.<br>

</div></div></blockquote><div><br>I can't say definitively how to check but I was using the in-kernel version for 2.6.26 (debian lenny) and got the following in my dmesg:<br><div>ivtv: Start initialization, version 1.4.1<br>
Which is newer than the one you reported below.<br></div><br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"><div><div class="h5">><br>
