Hi,
I've recently installed a Hauppauge WinTV Nova-T DVB (the newer 90002
model with the Conexant chipset) card into my machine, successfully
loaded the driver module and tuned in to a channel through the normal
scan/tzap method.
However, when I play the stream in Xine or MPlayer the picture is
extremely jerky and choppy, as is the audio stream.
MPlayer outputs a 'Your system is too SLOW to play this' message, but I
would have thought it was more than capable of playing this (AMD Sempron
2300, 512Mb RAM, Abit VA-20 Socket A VIA KM400A chipset). Neither CPU or
RAM utilisation during streaming go above 25%!
Dmesg shows the following info when playing the stream:
....
....
cx88[0]/2: [dc0825c0/0] cx8802_buf_queue - first active
cx88[0]/2: cx8802_restart_queue

cx88[0]/2: queue is empty - first active

Is this a problem with data transfer across the PCI bus or something
similar? Any help greatly appreciated, as I dont seem to be having much
luck with any cards recently!
Cheers,
Mike
