My thoughts about this phenomena:
- Although the iTVC16 (PVR500) is a cheaper version offering only
encoding, but
provides better quality over the iTVC15 (PVR350)
- The used tuners are different for PAL as for NTSC on a PVR500 and a
PVR350. I read previously that channels are not equally wide.
Are some of the frequencies maybe misinterpreted ?
Did somebody try to change the frequency a little bit (this will
result in a new EPG source for the PVR350) ?
- My problem channels (West-European, Provider Cablecom Zürich) are:
ORF1 S5 133.23
RTL K6 182.66
DSF K24 495.23
Eurosport S17 274.48
I'm using ivtv-0.4.0 and a PVR-350 and Cablecom Zürich, don't have any
banding problems on ORF1. (haven't tried the others yet.)
Attached are two scripts,
tune set the channel from the channel name (you may need to tweak tune
to use the correct device.) a simple bit of jiggery pokery to set the
frequency from bash to the nearest value.
ivtv-test set the frequency and sends the output to /dev/fb1 (ivtv-fb)
The picture is good on my Acer monitor. (much better that the crappy
s-video output from my Asus PCIE card.
