I am trying to capture packets when dialling up, and can select the

However, when looking at the packets, all I get is a long list of:

Ethernet? That means you're probably doing this on Windows.
If so, try doing a capture with WinDump and with the "-s 0" flag (to
ensure that WinPcap isn't deliberately limiting the packet size during
capture) and the "-w" flag to write it in binary format to a file, and
then try reading the file. ("windump -D" will list the interfaces, with
names and numbers; the number given for an interface in the output of
"windump -D" can be used as an argument to the "-i" flag to get WinDump
to capture on that interface.)
Then try reading that file with Wireshark; if you get the same problem,
this is almost certainly a WinPcap issue - report it to the WinPcap
developers:

In step 5, report, in addition to all that information, any special
networking software you might be running (firewalls, VPN software, etc.).
If you're not doing this on Windows, please tell us what version of what
operating system you're using.
