Yupeeee! So this device definitely works in dual channel mode... I will try to watch it via vlc remotely - on other box, via network... but it requires a bit of time to prepare (see above :) ). > If you want to test the second tuner make sure the channel is on > another mux than the one you're watching in vdr-sxfe or both will be > received by only one tuner... > Yes, that's clear to me.

It happened I did not test pressing Tab key until now in vdr-sxfe... Anyway, thanks for pointing to the config file, I understand it now much better.

In my eyes this is a key information and should be properly highlighted here.

I feel it could be a primary interface for all my needs. There is just one big issue remaining - character encoding in all output, be it info text displayed when 'I' is pressed in OSD, short text displayed when channels are switched with 'up' or 'down' cursor key, or anything in web live interface. In slovak language (or czech, as czech TV is watched here quite often as well) we use a lot of various accented characters. All of them are displayed as ?a in OSD display (while it could be a with umlaut or accent grave - two various sounds actually), in web live they are displayed as =C3=82a instead of =C3= =A1 as it should be. I did not have any experience with writing accented characters short of copy-and-paste method, so solving this may be obvious, too, I just have no idea, how. So, basically, I am quite impressed with VDR and its web live plugin, my DVB-T stick seems to be just working really well. Thanks for your support. Regards, Milan
