Linux SW for a new HTPC - Page 2

Have the hardware requirements for MythTV/Mythbuntu changed since 2008? I started to build one in 2008, but abandoned the project and want to retry again. I have an ASUS P5E-VM HDMI motherboard, Intel Core 2 Duo E4500 2.2 GHz, 6 GHz RAM, and a dual tuner HDHomeRun and just purchased a 2 TB Green AV hard disk.

I inserted my spare NVidia G310 card into this build and decided to install Mythbuntu/MythTV. I'm still working on getting it configured to use the HDHomeRun, but I just got the opportunity to pick up a Core 2 Quad 2.4 GHz (same chip as in my main PC which still serves me well) and a Hauppauge PCi card. Would it be worth buying the Quad Core chip and replacing my Core 2 Duo E4500 2.2 GHz or will it mainly add more heat to my HTPC?

I'm thinking of putting the Hauppauge card in my PC so I can watch OTA TV on it (not sure if this is a simpler solution than installing a MythTV front end and trying to control or grab content from my HTPC over the network). In either case, buying a 2nd LCD monitor and hooking it up will allow me to get rid of the 27" TV and Comcast digital box ($5/month), but I'm not too sure about how to install MythTV (and Mythbuntu?) onto an existing Ubuntu system without wiping it out.

To just record/watch programs on the backend, a smaller CPU is sufficient. If you want to do anything else, like commercial flagging or transcoding, then a larger CPU would be a plus. If you also want to watch internet video, which is usually Flash video, then a larger CPU would be a must have.

You can watch video recorded on a MythTV backend on any networked PC. Just install the MythTV Frontend:
Code:
sudo apt-get install mythtv-frontend

There are many plug-ins available for the frontend. You can install them one-at-a-time, or do a mass install:
Code:
sudo apt-get install mythplugins

I have the frontend installed on my laptop. And with N-Wireless, I get a perfect picture from the backend.

I plan on doing commercial flagging and possibly watch some Flash and Youtube videos.

Will the MythTV frontend be sufficient to test a USB tuner just for watching OTA TV? The USB tuner (non Happauge) works with Windows 7 on my laptop, but I don't know if it works with Ubuntu.

Thanks.

If you want it to support a tuner, then you need a full install:
Code:
sudo apt-get install mythtv

What would be the most appropriate Card Type to select in the Capture Card Setup for a USB tuner (PCTV HD stick)? MJPEG capture card?

For all USA OTA digital broadcasts, select DVB as the card type.

You may first want to make sure your card is working before you do anything else. Start the system without the card plugged in. Then display a list of USB devices:
Code:
lsusb
Take note of the devices is says you have. Also, output a list of driver modules currently loaded on your system:
Code:
lsmod

Now open a second terminal, and enter this command:
Code:
tail -f /var/log/syslog

Now plug the USB tuner into a USB slot. Linux will detect it and display messages concerning it. Look for any messages that talk about firmware, if it is looking for any and if it finds it. Also, rerun the lsusb and lsmod commands. for lsusb, the device ID can be Googled for driver info. The lsmod output will list newly loaded drivers at the top of the list. If the /var/log/syslog output has no message concerning firmware, run this command:
Code:
dmesg | grep firmware

With this info you can find out:

1) What Linux calls your USB tuner (lsusb).
2) What drivers it uses (if they automatically load).
3) What firmware it needs to load (if any), and whether or not it finds it.
