April Meeting Report

by Ron Roberts for Don Kassebaum

Shortly after the pizza and drinks were ordered, the waiter tolds us that there was a phone call for Brad Knowles. We didn't snap to it, but it was the speaker for the evening trying to get directions. M Hmmet from the Austin Linux User's Group (ALG) suggested that CACTUS and ALG have a joint meeting sometime.

The waiter must have given good directions, because Ronnie Escobedo showed up at about 7:30. He was short one power cord, and ironicly, we had no video projector for a talk about MythTV. Some members rummaged through their vehicles looking for a power cord, to no avail. So Randy Zagar drove home and got one.

Ronnie brought a laptop and his MythTV box. He said it took him about six hours to build it originally. He lamented that he had just upgraded it to Fedora 6, which was a most painful experience. He usually uses a live CD to test a release, but that doesn't ensure that MythTV will run on it. Like Tivo, MythTV is a personal video recorder. By default, MythTV edits out commercials. It can fast forward, pause, and rewind like Tivo. Ronnie said that the commercial detection mechanism is 99% accurate. It looks the the station logo to fade to black.

There's an online program guide that you can point your MythTV to. There are also themes to customize your box. There are many plugins available, including one to burn DVDs from your stored programs.

MythTV supports several video capture card, including Hauppauge and Homerun. You can stream video or music to your cell phone--something Ronnie has done because he has a flat rate phone plan. There are plugins for Weather, photo galleries, and others.

Ronnie put his MythTV box together himself. It's a 1 gigabye processor with 512 megabytes of RAM. It can record and play simultaneously. Support for HDTV is new. HDHomeRun from 9th Tee Enterprises will do HDTV only for about $ 170. Ronnie said that regular broadcast TV cosumes about 2 gigabytes of disk space per hour.

Ronnie also got a MediaMVP wireless front end so his kids an download videos by demand into their room from the MythTV box. He explained that four year olds are hard on DVDs.

Ronnie's box was a Silver Case designed for home media applications, but he has added hardware to it as well. He's put about $ 1,000 total into the unit. Mostly he filled it with hard drives. He actually had to remove one because he was stressing the power supply and fans.

Thanks to Mangia Pizza for the hospitality, and Ronnie Escobedo for the excellent presentation.

Directions to Meeting Location

CACTUS meets on the third Thursday of each month at the Mangia Pizza (Gracy Farms location):

Mangia Pizza - Gracy Farms
12,001 Burnet Road at Gracy Farms Ln.
Austin, TX 78758
(512) 832-5550
http://www.mangiapizza.com/33/Gracy_Farms.html

This location is approximately 2 miles north of our previous meeting location at ARL. Note that the Mapquest map on Mangia's web site is slightly wrong.

Mangia pizza is on the north-east corner of the Mopac service road and Gracy Farms Ln.

From 183 north of Duval Rd.:
Take the Duval Rd. exit on 183 and turn left onto Duval Rd. When you get to the intersection of Mopac (Loop 1) and Duval Rd., make the left turn as though you were going to get onto Mopac North (this is Gracy Farms Ln.). You will see Mangia Pizza in front of you to the left at the traffic light. Turn left and then make an immediate right turn into the little store cluster.
From 183 south:
Take the Burnet Rd. exit on 183 and head toward UT Applied Research Labs (ARL) as you would normally. Instead of going to ARL, continue on Burnet Rd. In approximately 2 miles, Burnet Rd. will fork - to the left will be Duval Rd. continuing straight will bring you to a traffic light (at Gracy Farms Ln.). You should see Mangia Pizza on your right. Continue through the traffic light and make a right turn into the store cluster.
From Mopac:
Exit at Duval Rd./Burnet Rd. From the south, continue on the service road. Continue straight at the traffic light to the next traffic light just a little bit further up. You will see Mangia Pizza in front of you to the left at the traffic light. Turn left and then make an immediate right turn into the little store cluster.

From the north, make a left turn onto Duval Rd./Burnet Rd. and then an immediate left turn (as though you were going to make a U-turn back onto Mopac) and there will be another traffic light where you will see Mangia Pizza in front of you to the left. Turn left and then make an immediate right turn into the little store cluster.

Note: If you pass Mangia Pizza, there is a U-turn on the left just a little past the store cluster. Follow the directions for Mopac coming from the north.
