The latest firmware is available here: [Link: homecontrol.philips.com]

Whether it will fix your stability issues, I don't know (my RC9800i is going back today as I just couldn't get the WiFi to work). Be aware though that it has been reported here and elsewhere that the latest firmware causes problems for some people with EPG downloads. I believe the previous version (2.78?) is available (but not from Philips) and seems to be the preferred version.
