If you think you have a heat problem, open the PC and run it until you have your suspected heat issue. Then spray the suspected component with freeze spray and view if you have any changes in the video output. Sometimes you can find intermittent thermal problems with freeze spray -- not always. On the other hand, how many people have heat problems with PVRx50s? It might be something else. I don't know how many people, but I'll raise my hand here. In the past 2 years I've had 4 PVR-250 cards die due to heat. The 4th one just gave out a couple weeks ago. First the tuner gets noisy for a month or so, then I start getting dropout that results in corrupted recordings and cause commercial detection to crash. Then I buy a replacement. I'm currently down to 2 cards again and am planning this time to replace with two PVR-500 cards. My system is a RedHat9-based Athlon 2600+ in a Gigabyte GA7VT600 MB with 512MB RAM, watercooled in a 4U rack chassis. The PVR cards get HOT and are the main source of heat inside the chassis. They seem to last up to a year. Of the 6 total cards I've had, none of them are still in service after over 2 years.

So if they're prone to overheating... why haven't you tried cooling them? James L.

[mythtv-users] Black Screen w/PVR-250 caused by overheat
I am experiencing a black screen on my pvr-250 after a few weeks of uptime with my myth box. I believe the cause is overheating because I cannot get my live tv to work until I shutdown and leave the computer off for about 30 minutes. A reboot will not fix this issue. I plan on adding a new fan to the system, but wanted to know if anyone has a solution or suggestions to fix this.

If you think it might be a memory leak or something like that then I can report that we're using ivtv-0.3.5v successfully. You might try upgrading that. Pretty painless test other than the 2-3 week wait to see if it helped. Good luck, Mark ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
