Question: I want to use my Sony Handycam (DCR-TRV840) & export video via RCA cables to a new HP Envy (It only has USB 2.0 and 3.0 inputs).  I have Windows 8.  Will this work?  Has anybody tried this?
Document: This is the fourth video capture device I've ever bought and used. It may be the best one as well. (My first was a video capture card which I couldn't keep after I had to buy a new computer, the other two were USB devices that just didn't work. )I had some trouble installing this because I downloaded and installed the driver for "Video 2 PC" from the ION website. Whenever I tried to start software to use the device to capture video, it crashed my system.
Purchased used ION Video 2 PC ConverterION Video 2 PC Analog To Digital USB Video Converter for PC. Cannot get it to provide glitch free recordings with Windows XP, Standard Video 8, and HP Pavilion computer.Provided all system info as requested in the service form. Tried all settings with software, added memory (per ION TS), added USBII ports (per ION TS), tried all ports (per ION TS), updated XP,  with no reduction in glitching/popping.
We have a great but older Sony Camcorder that is not compatible with our newer computers. We thought that we'd have to retire the old fully functional camcorder and spend hundreds buying a new digital recorder as windows versions higher than XP do NOT support streaming and do NOT accept anything but digital signals. This device solved that issue and works perfectly with any of our three Windows 8.1 computers. One note: Buyers using Windows 8 or higher, will have to upgrade the included software.
I had to use YouTube Video Editor to get the results I needed. If you want to edit or do anything of value you'll either have to purchase the upgrade (don't worry, there will be plenty of pop-ups to help with this) or use another editing program. For PC, Premiere (Pro or Elements) is still my favorite, but they are no longer the market dominators. Sony Vegas, NCH VideoPad, and VSDC all make decent video editors for the home user.
Could not get this work on OSX or Windows XP. Tried everything probably twice, consulted the website, downloaded drivers, spent weeks and ran out the window on returning it back to Amazon. The furthest I got was a message that said the USB device was not available or being used by another device.
At first the video was garbled. After reading an on-line trouble shooting guide I found out that not all USB ports are the same. My laptop has 3 ports, only one of which is an Enhanced USB host controller. The others are USB universal host controllers. After connecting to the enhanced one it works great. If it doesn't work, just try other ports until you get a good picture on the preview screen. You can find a list of your USB ports on the Device Manager in Control Panel.
Easy install & hook-up; some trouble with garbled audio until reinstalled USB drivers and deactivated anti-virus software. Then, was 1-2-3 to finished DVD. Will handle most any project easily.
It did not work with my Sharp View Cam on XP or windows 7 (2 laptops, 1 tower)  I tried my best.
Simply install the software on the provided disc and everything will work perfectly, including drivers and movie software. Don't go to the Ion website unless you enjoy confusion. I use a Dell XPS M1330 with Windows 7.The movie software on the disc is from Cyberlink and it is called PowerDirector version 8. I found that it has a lot of whistles and bells but, at least for me, has a steep learning curve.
I got it to work solid on HP laptop Win7 only by using downloaded drivers and simple EZ Video Converter fromION;Video 2 PC Mk II site.The DVD supplied software is really overkill and crashes on Win7.Mac Mini solid with Ezcap software supplied with DVD. Quicktime works good with captured files.None of the captured files will play on iPad w/o converting to iPad format.Over all pretty good buy. I would recommend to a techie friend.
Answer: It will work as a transport for the video/audio signals, yes. You will need some type of video editing program with which to capture the stream of data coming from your camera through this device. Windows Movie Maker, for instance. The best way (quality) to pull video from your camera is using its IEEE-1394 port (FireWire), but the HP Envy doesn't have that port.Edit - this worked fine for me. You can always return if there are issues.
