If you happen to do a lot of video encoding, you know that your computer can really drag while the process is carried out. Our own [Mike Szczys] transcodes videos at home fairly often, and because the process is automated, he doesn’t always know if a conversion is taking place in the background.

He has been tinkering with Larson Scanners recently and thought he could put everything he’s learned along the way to good use by using the scanner as a “busy” indicator for his PC. He hooked the scanner up to the computer’s parallel port, and took a few minutes to bang out some Python code that would alert him when his PC was busy.

He set his notifier script to launch along with FFMPEG, whenever his MythTV setup had something ready to convert. The Python script drives a pin on the parallel port high, triggering the Larson Scanner’s animation. Every minute, the script checks the status of FFMPEG and continues to hold the pin high until the application exits. Once the conversion is done, the scanner goes back to sleep, letting [Mike] know that the coast is clear.

Another group of developers has stepped up to the plate in the never-ending attempt to integrate online streaming video with MythTV. The new plugin is called MythNetVision and aims to bring streaming and downloading video functionality both easily and legally. That means without violating the terms of service of the providing website.

We’ve seen so many attempts that fell short it’s easy to be skeptical about the chances of this plugin actually working. Plugins like MythStream and MythVodka worked only temporarily before breaking and never seemed to provide a reliable option. Many people have tried adding Boxee, Hulu Desktop, or XBMC integration by launching these separate packages via the MythTV UI but that’s far from a clean solution.

It looks like MythNetVision is taking a slightly different approach. Although not yet available, the designers have built the plugin in two parts. The frontend is a fully skinnable user interface that parses RSS feeds to provide the hooks needed to browse, search, and view video. Depending on the content, a browser may be spawned to play the video, it may be played within MythTV’s normal player, or a separate download thread can be launch with video following after the appropriate buffer level is reached. The RSS feeds come either directly from the provider, such as the Revision3 feeds, or a scraper can be written to provide custom RSS feeds from sites that don’t have them.

We’ve seen a glimpse of the progress and we’re optimistic that we’ll see a reliable plugin. Early adoption and user script contribution are the best way to help ensure this so keep an eye out for the public release of this package.

Boxee, the free media center management and streaming application, is now available for Windows platforms. We’ve been following the developments of Boxee since we first announced its alpha this time last year. At that time, it was only available for OSX with promised Ubuntu support. We were a bit skeptical about the interface noting, “Unfortunately all the dynamic resizing, animated, sliding, floating info boxes make it behave like the zooming user interface’s retarded cousin”. Our interest in Boxee was almost entirely based on it being a fork of XBMC, the media center project developed for initially for hacked Xboxes. It was interesting to see Boxee become the interface of choice for hacked Apple TVs and then go mainstream with a big push at CES.

Have you been using Boxee as your media center? What do you love/hate? What about alternatives like XBMC, Plex, or MythTV?

A friend of ours recently purchased the Popcorn Hour. This set-top box can stream video from a network or usb hard drive using practically any codec or container format, can be configured to download torrents with an internal hard drive, and supports a number of web services including YouTube and Flickr. The Popcorn Hour is at least a fair value at $180. The downside? It doesn’t come with a hard drive or WiFi.

The lack of internal storage might be deal-breaker for you; if so, the Myka could be a better fit. In addition to coming in 80, 160, and 500GB flavors, this device opts out of all proprietary content delivery services in favor of open ones. It has strong synergy with BitTorrent.com built in, downloading directly from it or a number of other torrent services like ISOHunt. Prices range from $299 to $459.

If you’re like us, you’d rather build your own Linux media streamer. All you need is a spare computer. Cheap graphics cards with component out are fairly easy to acquire. For a frontend, you could use DVR software like MythTV, but that might be overkill. Check out the Linux port of XBMC which is what the Mac version of XBMC we covered previously is based on.
