[linux-dvb] WinTV-Nova-T: cx8802_restart_queue

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: cx8802_restart_queue: queue is empty
cx88[0]/2: queue is empty - first active
cx88[0]/2: cx8802_start_dma 752
cx88[0]/2: setting the interrupt mask
cx88[0]/2: [dc0827c0/0] cx8802_buf_queue - first active
cx88[0]/2: cx8802_restart_queue
cx88[0]/2: cx8802_restart_queue: queue is empty
...

Specific sections of lspci -v:

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
