You said it freeze on videos, maybe some videos require more bitrate/access speed?
You can post the picture (on filetrip) with the part showing IOS > 200
but what is interesting is only to know if your slot249 has base56, that's all I need to know.
yea videos, and sometimes when loading new areas.
here is 249....
IOS249[56] (rev 21010, Info: d2x-v10beta52): Trucha Bug, NAND Access, USB 2.0
thats exactly how it is. That is the same for slot 250, except says [57]
