Virgin Cable on MythTV

I've been trying to get my TechnoTrend C-1500 DVB-C card to connect to Virgin Media and tune in the FTA channels.

Linux detected the card and configured it automatically. The TechnoTrend card has been available for some time now, so support is good.

It took a while to work out the correct numbers to give to the tuner program, but I eventually found out how to boot into the Engineering menu of the Samsung SMT-2100C STB, which contains the current settings. I used DVB-Tools on Linux to scan the channels. Here is the config file for scandvb:

# Virgin Cable (UK)
# freq sr fec mod
C 666750000 6952000 NONE QAM64

This worked well, detecting 344 channels, 94 of which were unencrypted (Freeview channels and radio).

My main problem now is signal strength - I'm getting 0-1%, which is just not enough to watch most of the channels. I think the quality and shielding of the cable I've used (TV aerial RF) is much less than Virgin's and I'm connecting to the end of a fairly long extension. I'll try to get a better one this week and give it another go on a machine nearer the Cable access point.

Free Books and Sheet Music

Project Gutenberg has out-of-copyright books and Mutopia has out-of-copyright sheet music.

The Web is a wonderful thing... Yay!

Technotrend C-1500

Yay, my Cable TV card has arrived! It has an add-on CI reader, into which I can plug a module that will read the smart card used to decrypt paid-for Virgin Media TV channels.

It may be some time 'till I get it up and running with MythTV, but I'll post when I do.

Graphviz

Until recently I've been using an open source diagram creation program called Dia. It's an adequate (if a little clunky) alternative to Microsoft Visio. You drag and drop different shaped blocks and join them together using stretchy arrows, all of which can be customised to look as you wish.

However, as a programmer, I want to lay out a set of relationships and let the software work out the best way to represent them.

Enter Graphviz, a set of open source tools for doing just that.

I used the DOT language to describe my MythTV set-up as a collection of elements connected together with wires, IR and Bluetooth. It also allows you to group similar elements together and even create subgraphs.

It really does an excellent job of laying out a readable diagram and I'm itching to find some way to use it in production.

Note to self

I took the Carlsbro Orion 10 active speaker that I bought for Jay's birthday back to the shop when it stopped working. I'd checked the fuse in the plug and thought that the damn thing had just broken down after an hour's use.

Embarrassingly, when I took it back to the shop, they quickly pointed out that the internal fuse had blown (very kindly not abusing me for my stupidity).

In future I promise not to take things back to the shop when they blow a fuse!

Bass Guitar

Listening to music in the car back home from rehearsals last night, Penny suggested that we learn the song Paranoid Android by Radiohead, with myself on guitar and Penny on bass.

There's only one tiny snag in this plan, Penny can't play bass... yet!

She does have a lot of experience singing alto vocal parts (kinda like female bass singing) and can already play other instruments and read music, so presumably she'll have a natural ear for basslines.

We shall see... I've bought a beginner's bass guitar book, a Muse notation book, some new Super-Slinky's and a couple'a plectrums.

We'll start tonight!

Around the World with Gilbert & Sullivan

Over the last couple of weeks, I performed Around the World with Gilbert & Sullivan with the Bournemouth G & S Operatic Society. This was a compilation concert of Gilbert & Sullivan mixed with other popular music, that went down very well and was highly enjoyable to be involved with.

Auditions for the next show, "Gondoliers" (Half term, Oct 2007) take place in a few weeks time, so I'd better get practicing those audition pieces.
