I have played on xbox for the last few years, I had a 1st run xbox, for long time and experience a lot more crashing and freezing on it. It died a year ago got a new one (just an arcade) and I noticed it has a lot less issues. But I still crash in besieged. Im sure this is a cashing issue. I big help would be letting the game go 100% hd like most of the DL xbox classic games you can get now. Accessing the disk is one of the problems. But Im not sure SE or MS care. SE still prints the disk now an again but I think the are done supporting it Xbox. A good way to tell this is they have not add any achievements to the game. And there as been no add's or updates form x-box live on the updates to the game. For besieged i find the siting in the corner thing after about 29 min's works. The sound track works for the lock up reboot 100%.
I still love being able to use the xbox sitting on the couch with a wireless keyboard and controller on Large tv.
