Boxee Live issue

[denox]

I was very excited when I received my boxee live dongle.
Installed and connected using cable (included antenna couldn't find any channel), scanned (looong time) and found bunch of channels.

Now the issues:

1. There is no data on TV guide. Zip 07024, provider Time Warner

2. When browsing channels suddenly weak or no signal screen appears and BB freeze and has to be rebooted.

3. When browsing channels, out of sudden BB freeze on random channel. BB has to be rebooted.

4. Every time exiting Live mode, BB freezes and has to be rebooted.

Are these known issue?
Anyone having same issues?
