next in thread | raw e-mail | index | archive | help
I've installed a PVR-250 card in a system running 5.4-STABLE. The system was built from code downloaded around April 15th. The system is an AMD Athlon Slot A 750 mhz processor running on an Asus K7V-T motherboard. I have 1gb of PC-133 RAM installed. I'll include dmesg output below. My ultimate goal is to build a PVR based on MythTV. As part of this goal, I've installed the pvr-250 port and mythtv ports from http://mythtv.son.org/tiki-index.php?page=Multimedia+Drivers. I can view tv with either 'mplayer /dev/cxm0' or the 'Watch Live TV' function in MythTV but the picture quality varies from moderate to poor. The poorest picture comes when there is the most motion so I suspect it has something to do with encoding or decoding. Then anywhere from a few to 30 minutes, the machine just locks up. No error. No nothing. Only power cycling the machine will free it. While watching a stream from /dev/cxm0, the cpu seems to run around 50% - 70%. Is this a reasonable usage for this cpu? Any ideas on what I may do to optimize and or stabilize my setup?
