In fact, it doesn't freeze all the time! Curiously, the behavior of UDVD2 (or VirtualBox, depends of the point of view I guess) is quite erratic. I rebooted the VBox machine several times. Sometimes it works fine (UDVD2 don't freeze), sometimes it freezes for a short moment (like 5-10s), and sometimes it freezes an entire minute.
On a side note, it seems that VBox has also some troubles with FDAPM - half of the time, when I try FDAPM POWEROFF or FDAPM COLDBOOT, it freezes the virtualbox machine instead of actually halting or rebooting. edit // I examined settings of the virtual machine, and noticed that I had set the 'CPU capping' to 30%. I moved the setting to 100%, and then the miracle happened - both UDVD2 and FDAPM stopped freezing! I rebooted many times to be sure, and it all worked every time. Emulation...
