Over the weekend we got to watch a full movie with Patrick for the first time: Star Wars! In the past he hasn’t wanted to see them because at some point he came to the belief that all movies are scary. But someone from his class, I think, convinced him to want to see this.

And, finally, a movie sounded really good in our livingroom!

For a really long time now we’ve been using a Cambridge Soundworks DTT 3500 Digital 5.1 Surround Speaker System to make TV and movies sound better in our livingroom. It worked pretty well, overall, even making the sound from our MythTV PVR system go out through it.

When I had to replace our 8 year-old dead TV, I was hooking up everything and found the Cambridge Soundworks box wasn’t actually usable anymore. The new Samsung LE40R74BD television (absolutely gorgeous) had a single red/white pair of RCA plugs for audio out, and no way to feed sound via the optical or coax inputs needed for the surround sound system. Hmm.

So after a while I finally got a sound receiver to connect everything. The Sony STR-DG700 receiver can do everything. (Continuing a past habit with TVs, cars, and other things, we bought the floor demo model at a discount.) Well, it can do just about everything—the DVD input can only come in via digital coax, not optical. And, the Sony guy is ordering us the proper remote for it because they couldn’t find it anywhere.

I reused the Cambridge speakers for this receiver, since I felt they would work perfectly fine for what we need. The temptation for the expensive Bose speakers was there a little, and then there’s the uber-expensive Bowers & Wilkins speakers available up in Blackrock. But after the TV and then convincing myself to get the receiver, it’d sure be cool to not buy anything else.

The five little black Cambridge speakers did a fine job. The DVD player’s digital coax line went into the receiver and made the sounds of movies jump out at us. It was wonderful, even if there was a missing piece: the biggest part of the speaker set is the subwoofer which gives the happy thundering sounds and dramatic effect. But ours wasn’t working—the receiver has a Pre-Amp Out plug for the subwoofer, which a little reading helped me understand: the subwoofer’s supposed to have its own amp, its own way to take the sound and give it some oomf. Since I was no longer using the DTT3500’s black box of buttons and dials, there was no amp for the subwoofer anymore.

I asked around and looked at some sites and called some shops, but it seems like buying a single subwoofer isn’t a cheap exercise. They were hundreds of Euros, mostly. Not worth it to me for the single device. Natural thought progression tossed my brain back into the Bose-is-so-cool arena. But wait…

Maybe we can make the receiver give its output to the Cambridge box so it could do the work for the subwoofer? Yes!

I discovered that there is one optical output on the Sony receiver: MD/TAPE. I plugged an optical cable into that, and put the other end into the Cambridge box. Plugged its subwoofer into the subwoofer contacts, and played Star Wars.

Oh my. That’ll work for a while. 🙂

I recently figured out how to make it possible to install the mythfrontend client on other systems in our house rather than just on the TV in the livingroom. e.g., I can watch the news in a window here upstairs in my office while I’m working (cough).

The fundamental step I had to take was running mythtvsetup and change both the host and Master Server IP addresses to be their real address (192.168.20.23) instead of 127.0.0.1 as had been laid out in the instructions.

I followed the instructions at

http://www.bus.ualberta.ca/yma/mythtv/Mythtv.htm

for fixing remote permissions which boiled down to

% mysql -u root -p rootpw_for_mysql
mysql> use mysql;
mysql> SELECT Host, User, Select_priv, Insert_priv, Update_priv, Delete
_priv FROM user;
mysql> GRANT ALL PRIVILEGES ON *.* to mythtv@”%” IDENTIFIED by ‘mythtv’
WITH GRANT OPTION;
mysql> flush privileges;
mysql> SELECT Host, User, Select_priv, Insert_priv, Update_priv, Delete
_priv FROM user;
mysql> exit

With that, the SuSE 10.2 desktop system I’m using now could use the various mythtv* packages, just pointing it at the .23 backend server. Not everything works…going into Watch Video doesn’t work, but presumably because I’ve got to tweak a setting somewhere. Likewise, I have to have music mounted as /video/music if I try to choose Listen to Music. But watching recordings and live TV works just fine.

Of course looking now, I see that Jarod Wilson’s Tips’n’Tricks to his awesome HOWTO on installing MythTV makes mention of all of this. Oops. 🙂

This Thursday is Yuri’s Night. I know nobody who celebrates, and even if there was a party closer then NYC to me I don’t think I could make it. Nevertheless I will try to entice my family out to dinner that evening and I will order a Vodka drink and, assuming dictionary.com is correct, I wall say ваше здоровье and watch my wife and child look inquisitively at me while I try to explain it to them. Apart from, maybe 萬虎, Ю́рий Гага́рин was the first human is space. You can’t take that away from the Soviets.
