Read Ahead Buffering

[Speedy710]

Is there a way to set read ahead buffering in RAM of a significant amount for VCD?

The reason I ask is that I am streaming DVD and Blu-ray disc ISO images from a Windows 7 media center to other Windows 7 PCs connected to other televisions and the playback stutters or hiccups most of the time on the remote machines. I know it is because of the remote streaming because all machines play local ISOs fine and I cannot upgrade the network any further as it is already switched gigabit. The read ahead wouldn't have to be that large as the hiccups never last that long and given that Blu-ray's maximum bitrate for AV is 48Mib, a 128MiB or even 256MiB buffer should smooth out any latency on the network. I have tried the buffered IO setting but that seems to have no effect on the problem. I have tried Daemon Tools as well and get the same issue.

So, any thoughts on if this can be done with VCD?

Thanks in advance for any help.
