This is s simple guide to help the first time buyers of portable PVR hand-held media player/recorders. Apple's introduction of their video IPOD players has accelerated the new product introductios portable video media players that use high capacity hard drives. The four most popular maufacturers of these units are Archos, Creative, Samsung and Cowon. There are numerous other manufacturers like Mustek, iRiver, etc. that orignate from the far eastern countries that are also sold in the North American marketplace. The key purchasing criteria based on my past experience with these players is: 1) Size and Screen Resolution. How big is the screen. 2.2" diagonal should be a bare minimum and anything above 3.5" is probably optimum. Screens max out at 7" to 8.9" but you begin to sacrifice portability (heavier units) and battery life (shortens as you go to a larger screen) as you move to these larger screens. 2) Video File Format support. Does it support MPEG I, II MPEG 4, or DiVX as well as the Microsoft AVI format? Are the Sound CODECs compatible? Does it playback action scenes artifact free without blocky or blurred scenes. Soes the soundtrack synchronize properly with the video? The CPU must be powerful enough to decode the video and audio files for smooth video playback performance but also be eneregy efficient for long run-times on batteries. Try before you buy to ensure that the videos are watchable on the small screen and that the sound is of a high enough quality for extended viewing periods. 3) Battery Life - Average for these units is 2-2 1/2 hours of continuous viewing. Some units like the Cowon claim up to 8-10 hours. Your mileage may vary based upon the brightness setting of the screen and the codec playback settings. Anything over 2 1/2 hours is exceptional battery life for a portable Video unit. 4) Does the unit feature full video/audio recording capability...that is can you use it as a PVR (Video Tape Recorder) to tape shows from your cable box or movies from a dvd or other video analog playback source? Can you plug in an optional video camera? Does it allow you set recording schedules for taping shows at different times, dates and channels un-attended? How flexible is the programming? Is there a break-out box/dock or can you do everything with a set of AV cables? 5) How complete is the documentation? How easy is it to get customer support? Can you upgrade the hardware with BIOS upgrades to support new features or file formats? What is the warranty period? How easy is it to get accessories? Is the battery fixed or removable. Can spare batteries be obtained easily? Can I get a 12 volt Car DC adapter for the unit? How hard/easy is it to obtain and connect an external third party extended life Battery Pack? 6) Durability and build quality - How solid is the player.What materials are used? Aluminum and/or plastic? Does it feel fragile when holding it? How easy do the controls move? Is there a hold/resume feature? Can it also be used as an external USB drive to store PC and multimedia files such as jpegs from digital cameras? It is also rumored that both Microsoft and Sony are working on a portable PVR Video media player. The Sony unit will most likely carry the Video Walkman moniker and the Microsoft unit will have tight integration with their Media XP PC software and XBOX 360 infotainment systems.

I tried to be manufacturer agnostic and the usual disclaimers apply. Let the buyer beware and if the advertising claims seem too good to be true, they usually are. Also try to buy from a reseller that has a decent return policy so you can try before buying. Additional research is also a good thing. PC Magazine writes pretty objective reviews for these type of devices. Lastly, if you found this guide to be helpful, please vote and say you found this guide helpful.
