After much research here in the forums, I finally was able to call tech support here in Australia. After discussing the issues associated with my Slingbox Solo and the steps I have already taken by following the diagnostic steps posted here, the techie has intially determined that my problem is also with capacitors. They have sent me via email, an eparcel label (prepaid, user printable postage) and asked me to send the unit back and they will send me a new Slingbox Solo.
They told me that the capacitor problem isn't as widely spread in the Solo as the HD, but it does indeed sound like the same problem so many people are experiencing here.
After weeks of frustration, of pulling my hair out over this, I must admit the call to tech support was easy to make and very quick as far as tech calls go. I mentioned that I had followed all the suggested diagnostics here. I told them my solo was freezing up anywhere from initially launching the software to withing 20 to 30 minutes of streaming. They had me check the lights on my solo as well.

Thanks to all who helped diagnose this issue.
