What is blocking my ports?

XP SR2
I am having getting Tivo to 'talk to' my PC over a wireless network.
Went to Tivo support and forum but was unable to get an answer.
I have a Dell router.
PC ic connected to the PC via ethernet.
Tivo is connected wirelessly
Notebook is connected wirelessly.
PDA connected wirelessly for net use only.
PC, notebook, and PDA work.
Tivo lists an IP address and signal strentgh is good to excellent.
Notebook can see Tivo and can download files to HD.
PC can not find Tivo.
However, when I open Tivo sw on the PC Tivo's correct IP is listed.
When I ping Tivo (ping xxx.xxx.x.x), I get 4 packets sent/received.
Per Tivo, I entered URL https://xxx.xxx.x.x into my browser, entered
name and password, and the PC can see Tivo but can not download. Tivo
say this confirms the problem is a blocked port.
I have literally uninstalled Norton antivirus and firewall, disabled XP
firewall, and tried again. Keep getting a mesage from Tivo (on the
PC)about an error on trying to communicate which Tivo says indicates a
port problem.
I have been told by an expert (a friend how knows more than I do) that
since Tivo can talk to my notebook through the router, the problem with
the PC is not the router or the router firewall.
I have a list of ports to open but since, at the time, I had no without
a firewall, I had no sw to tell to open ports or allow programs.
I have, btw, reinstalled the firewall and antivirus sw.
How can I find what is blocking those ports or, is it possble the ports
are defective?

Which ports does TIVO use? If you have that info you could use something
like PortQryUI to see if those ports on the PC are blocked. Use PortQryUI
from the laptop and query the PC to see the status of the ports.

PortQryUI is available from

Mike,
DLd PortQryUI and ran some ports. Unsure how much you need - 18 ports
total. I ran 5 at random. Results follow.
Firewall on PC and Notebook disabled throughout. Don't know if antivirus
matters in this.
Port 37 TCP
PC to Tivo - filtered
PC to Notebook - Not Listening
Notebook to Tivo - filtered
Notebook to PC - not listening
Port 123 UDP
PC to Tivo - listening or filtered
PC to Notebook - listening or filtered
Notebook to Tivo - listening or filtered
Notebook to PC - listening or filtered
Port 2190 TCP
PC to Tivo - listening
PC to Notebook - listening
Notebook to Tivo - listening
Notebook to PC - listening
Port 7288 TCP
PC to Tivo - filtered
PC to Notebook - not listening
Notebook to Tivo - filtered
Notebook to PC - not listening
Port 8081 TCP
PC to Tivo - filtered
PC to Notebook - not listening
Notebook to Tivo - filtered
Notebook to PC - not listening
If you need the whole list I will get it when I get more time.
Meanwhile, is this enough to be of any help?

You may well be right but I have literally uninstalled Norton Firewall
and disabled XP firewall. Still the ports are blocked. Am I missing
something?
