[mythtv-users] Nova T 500 Lock problem

[Rob]

o.k well as an update I decided that I'd messed around so much with my 
current rig that I should start again from scratch. So I reinstalled 
ubuntu, got the nova t 500 drivers rolling. And installed the standard 
package which is Library API version: 0.20.20060828-3.

Tried to do a full scan with an extended timeout on the nova t and it 
found nothing. Did a scan on my transmitter TheWrekinB and got some 
channels as before.

Imported it into myth and there we go it worked, watching bbc1 on myth 
as I type.

Cleared the channels list and did another scan but on the "existing 
transports", this found the same load of channels BUT none of them would 
display in mythfrontend, I got the "L__" problem, partial lock. So 
deleted all them, and reimported from channels.conf, they all work again 
bar the radio channels which won't play.

So my conclusions are that when myth imports directly from channels.conf 
its getting the right information, but I'm assuming because it didn't 
scan them itself it doesn't recognise the radio channels as such and so 
treats them as a normal channel, would that be consistant?

I say that because the later versions of myth which I tried previously 
all seemed to use channels.conf as a pointer and proceeded to scan those 
transports listed there, so in effect doing its own scan, again when it 
did the scan itself the channels would never display.

So presently I either need to figure out a way to get myth to treat the 
radio channels as such or get the scan to work correctly. Does anyone 
have any pointers towards a solution? Personally I think solving the 
radio bug would be simplest since at least I'm part way there at the moment.
