Consecutively tuning several times to the same channel results in 1/2 of the time channel lock with almost 0 UNC and 1/2 of the time with high rates of UNC. That second scenario makes the mpeg stream unwatchable (even no output in dvr0 most of the time) A sequence of "tzap -r channel_name" results in a cycle of OK/KO tuning results. After an "OK" tuning (no BER, no UNC, signal level aprox 0x6600) I always get a "KO" tuning (high BER, high UNC, signal level aprox 0x7700) Note that "pseudo-randomly" means that sometimes it doesn't happen at all but, when it happens, you always get the 50%-50% KO-OK sequence. Unfortunatelly, I'm not able to reproduce it on demand, it depends on some unknown conditions.
