</div>I had the same problem and stayed on kernel 2.6.24 with my bttv cards.<br>
I did some investigation and the problem seems to be related to the<br>
changeover to V4L2 in <a href="http://2.6.25." target="_blank">2.6.25.</a><br>
<br>
This message <a href="http://lkml.org/lkml/2008/1/6/83" target="_blank">http://lkml.org/lkml/2008/1/6/83</a> describes a patch to the<br>
bttv driver, but if you look at the 2.6.25 kernel source you will see<br>
that it isn't there. If you apply this patch (like I tried) then it<br>
will get further, it won't lockup but I didn't get any video either.<br>
<br>
I e-mailed <a href="mailto:video4linux-list@redhat.com">video4linux-list@redhat.com</a>, <a href="mailto:v4l-dvb-maintainer@linuxtv.org">v4l-dvb-maintainer@linuxtv.org</a><br>
and <a href="mailto:mchehab@infradead.org">mchehab@infradead.org</a> reporting the problem, but the e-mail never<br>
appeared on the list and I had no reply from the maintainer.<br>
<br>
There looks like there is a different patch for this problem in the<br>
latest v4l git tree and mainline kernel, but I haven't tried them:<br>

<br>
I am waiting for kernel 2.6.26 and hoping that it will work again.<br>
<font color="#888888"></font></blockquote><div><br><br>I rebuilt video4linux from ATrpms using today's snapshot, <br>and it worked.<br><br>Well, almost. If I try mythtv Live TV after rebooting, I get a green screen (but no lock).<br>
However, If I run mplayer before using mythtv, Live TV works just fine.<br>Maybe this is related to the nvidia driver I am using. I did not try the latest one (173.14.09).<br><br>I will ask Axel to make video4linux (20080622) available to the public.<br>
