Channel browsing does not work with channel browser (dvb)

[lukas.kasprowicz@…]

Hi,

first, this is not the same problem like 330.

When trying to use channel browser, to zap to another channel, in 7252, OSD shows "No Lock". After filling startchan with channel where to zap, it works without any problems. zapping back does only work by filling in new channel to startchan and restarting mythbackend.

I tried to zap, restart frontend, like in 330, but mythbackend was not availible anymore.

In backend log i found a frequency, where it zaps to and this frequency shows one more digit then the old frequency.

First initial tune:

Daniel, this one is exactly the "Magical-Adam-Egger-bug" we were trying to fix on my system two or three weeks ago. I'm now mostly able to switch to another channels without any problems. I only got this black screen with No-Lock once after I'd changed my startchan to a different channel. I had to kill my FE then and the strange thing was that the tuner died after the the FE was killed.

This appears to be a duplicate of #326.
