(No image ghosting, so that must have been related to the bad capacitors.)<br /> <br /> My theory now is that after some instances where the driver get's reloaded, the backend is still able to use the device, but sometimes it gets in a weird state where the recorded image has this flashing along the top edge.<br /> <br /> Most of time for me (9 times out of 10) the driver reloading meant that the card could no longer be used for recording. I've only seen the flashing 2 or 3 times since I've started having trouble about a month ago. Stopping the backend and unloading/reloading the ivtv driver fixed the problem, temporarily, until the kernel decided that the firmware had failed had needed to be reloaded.<br /> <br /> Interestingly enough, the driver re-load never seemed to happen during a recording - always in-between recordings.<br /> <br /> For now, I have configured one of the analog encoders on my HVR-2250 and hooked up my DirecTV box to it, taking the PVR-350 out of commission for now until I can resolve the problem.<div><div><br /> </div></div></blockquote><div><br />So the question really becomes is it an <font color="black" face="Verdana,Arial,Helvetica"><font color="black" face="Verdana,Arial,Helvetica">ivtv driver or a myth problem, and how do we get a resolution? <br /> </font></font></div></div><br />-- <br />Tim Scholl<br /> </blockquote><p>My feeling is that it's an ivtv driver problem as I was able to observe the same flashing of the top 15% of the image when I ran "mplayer /dev/video0 -"</p><p> </p><p>How we resolve that is a question for a better man than me :-(</p><p> </p><p>Regards,</p><p>Dave.<br /> </p>
