Hi,
I bought a Twinhan Visionplus DVB-T USB recently after trying a PCI version and getting bad reception. I run Suse 9.1, currently with the latest dvb-kernel from CVS (three days ago) and a 1:st october kernel from Mantel (2.6.8.1).
Now, everything starts fine, the green light comes on etc… But I cannot get any picture. When using tzap I get the signal strength numbers:
stylus:~ # tzap tv3
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
tuning to 778000000 Hz
video pid 0x040f, audio pid 0x040e
status 00 | signal 3a6f | snr 0001 | ber 001fffff | unc 00000000 |
status 00 | signal 0000 | snr 0000 | ber 001fffff | unc 00000000 |
status 00 | signal 0000 | snr 0001 | ber 001fffff | unc 00000000 |
status 00 | signal 0000 | snr 0000 | ber 001fffff | unc 00000000 |
status 00 | signal 0000 | snr 0000 | ber 001fffff | unc 00000000 |
status 05 | signal 0000 | snr 0000 | ber 001fffff | unc 00000000 |
status 04 | signal 137a | snr 1d00 | ber 001fffff | unc 00000000 |
status 05 | signal 09bd | snr 0000 | ber 001fffff | unc 00000000 |
status 04 | signal 0000 | snr 0000 | ber 001fffff | unc 00000000 |
status 05 | signal 0000 | snr 0000 | ber 001fffff | unc 00000000 |
status 00 | signal 1858 | snr 2600 | ber 001fffff | unc 00000000 |
status 01 | signal 0000 | snr 0000 | ber 001fffff | unc 00000000 |
status 04 | signal 0b21 | snr 0000 | ber 001fffff | unc 00000000 |
The really weird part is that I got good enough values from my PCI based card for the same channel (not for others). I could watch TV flawlessly, see below:
stylus:~ # tzap tv3
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
tuning to 778000000 Hz
video pid 0x040f, audio pid 0x040e
status 1f | signal 5100 | snr 6200 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
status 1f | signal 5100 | snr 6200 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
status 1f | signal 5100 | snr 6200 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
So, my question is: What is going on? Has anybody seen this type of problem with the drivers?
Thanks!
Alwin
