As discussed in last week's Switched On, the PopCatcher Ripper scours FM radio stations to separate the music from the mumble and transfer songs to flash drives, memory cards and several brands of MP3 players. Using the product, one can harvest hundreds of megabytes of music without any service or song acquisition fees or touching a PC.

However, there are some limitations. First, while songs are captured as 192 kbps MP3 files, captured song quality will be less than that of purchased or CD-ripped tracks due to the limitations of FM radio. Furthermore, files are named according to the order in which they were captured. There is no automatic song identification, nor does the company provide an Internet-based song identification service for captured tracks. Radio stations are inserted for the album title field. Because of these analog disadvantages, developing a version of the PopCatcher technology based on HD Radio would be a natural future improvement.

The beginnings and ends of songs will also often be a bit clipped although this generally wasn't as much of a disadvantage as anticipated. Also, because there is no programming guide or way to set manual recording times, you cannot use it to record talk-radio programs, one of the key applications of the PoGo Products' RadioYourWay devices.

Before MP3 players, CD burning and even the Mini-Disc, there was the analog mix tape. Patient proto-playlist creators would wait as a needle hovered over vinyl, descending into a groove that would cue the synchronized pressing of 'Record" and "Play" buttons. The truly determined would stage vigils by a cassette-recording boombox, hoping to catch a telltale chord or DJ introduction to songs now offered on "FM gold" compilations.

Terrestrial radio recording has faded in the post-CD era. The original Napster established the PC as the epicenter of digital music acquisition. Portable players -- from last year's Sansa Connect to Archos Generation 5 players to the just-released Slacker Portable -- have only begun to break free from the PC's tether. Even these rely on broadband and WiFi for Internet service-based music discovery, making them pricey and relatively complex "poor man's" alternatives.

But new hope for the thrifty and technophobic is on its way from a Swedish company called PopCatcher. The PopCatcher Ripper records songs from FM radio and transfers them to an MP3 player. The product is no homage to the notorious Jack the Ripper, a depraved murderer who disemboweled destitute victims peddling sex, although that description approximates how the content industry characterizes entertainment pirates.

We all know that bit about a "speedy trial" doesn't exactly come to fruition in most cases, and after three excruciating years of battling innovation stranglers the DVD Copy Control Association, Kaleidescape has escaped unscathed. The firm's DVD ripping / streaming jukebox was under fire for obvious reasons, as it not only encouraged the ripping of "protected content," but it helped users rip and transmit the data around their network. The DVD CCA whined that the machine "breached a contract" when it crafted a product that enabled users to copy its locked-down material onto hard-drive based servers -- the judge, however, felt otherwise. In fact, it was ruled that "nothing in the DVD CCA licensing agreement prohibits the development of products that allow users to copy their DVDs," thus, no contract was breached at all. One down, too many to go.

We've become accustomed to seeing some good looking hard-drive video units from Korea's TViX, and the company's latest, the M-3100U, appears to be no exception. Besides having a sleek, HTPC-style case, the M-3100U can record video content from a TV, PC or just about any analog source, and can save it in MPEG 1 or MPEG 2 formats. The box is also apparently capable of HD output at resolutions up to 1080i, though we assume that's analog HD, given that this thing doesn't have HDMI or DVI, but does have component outs. We somehow suspect that, if you want a similar box with real digital HD, you're probably better off seeing what you can get from your cable company or waiting for a TiVo Series 3 box -- though neither of those may be quite as pretty as this one.

If you're still buying your music on shiny round discs and want to rip it on the go, the ¥19,800 (about $169) SeaGrand ez6 seems like a relatively painless way to get it done. Put a disc in the portable player, plug in a USB drive or SD card, and rip away. Of course, you won't have the usual conveniences of Gracenote integration and ID3 tagging, but if you, say, pick up a CD in an airport kiosk and need to get it onto your digital audio player by flight time, this will get it done.

Infiniti's G35 may be the most expensive CD ripper you ever bought (or lusted after, anyway). The new 2007 G35 has an in-dash system apparently outfitted with not only a CompactFlash slot, but a CD player that will also rip and encode your CDs for storage on an internal drive of unspecified size (we're really hoping the "9.5G" mentioned in the article is a model designation, and not capacity). Sure, it might just be easier to have a removable drive (or USB port) for dropping already-ripped or, um, downloaded songs into your car, but Infiniti must not expect the unclean to understand luxe doesn't always mean ease.
