I have an (old) Popcorn Hour as my Media Center and I got several Issues from time to time if I try to access my Shares on my pc like “Out of Memory” and such.

It’s actually easy to fix those issues (more or less). Just modify the following keys in the registry on your PC:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\LanmanServer\Parameters]
"IRPStackSize"=dword:00000039

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\LanmanServer\Parameters]
"MaxNonPagedMemoryUsage"=dword:2000000
