I too am getting the svideo noise. Popping, crackling, but also a strange periodic (30 Hz?) distortion, kind of like the audio dropping out. I have not graphically looked at the audio to see exactly what is going on. It is almost like it is playing back a frame of audio too quickly, running out of buffer, then waiting for the next frame of audio. I am still working my way backwards through the drivers to determine when this started. I am using an NTSC WinTV-PVR-150MCE. I can supply my modprobe.conf and dmesg dump but everything looks real clean there.
Thanks for all of the great work. Alan > Hi Chris, > > I dropped back to 0.3.3y. VBI teletext is much worse with 0.3.4a.
