PEDROBAL EyeTV3.0 essentially is the same app as version 2. Not much will have changed in the eyes of the user. It is easier to export to other formats. The export feature is flakey and unstable. Two out of three times I scheduled a recording, the export stalled in the middle so I was unable to view the movie on my iPhone. The worst problem with EyeTV is a horrendous memory leak. After running a few hours, the whole system slows down to a crawl. After taking a look in Activity Monitor I noticed that EyeConnect was using up over 900MB of real RAM (not just virtual), and that was while it had been doing nothing. I googled a bit and found that the only way to get my RAM back was to delete the file ~/iTunes/iTunes Music Library.xml, and Force Quit EyeConnect. This will help until you restart the system, after which EyeConnect again will eat up all RAM, so again you will have to delete the xml file.
Elgato's costumer support is of course lousy, they give you a support help ticket as a confirmation but I have yet to get a response from them now after a week. I would not recommend that anybody buys this product yet unless they are truly able to troubleshoot memory leaks.
