Sounds plausible.  At the moment the mpeg decoding is only used by the hardware encoding and the DVB people, and I guess that no-one yet has multiple hardware decoders (even if they were supported by the drivers...?)

I think in the UK we are getting data rates of between 2-4Mb/s, and you will probably find that your 802.11b runs at perhaps 3-3.5Mb/s max.  Also, I only have an 802.11a net, but I notice that bandwidth varies quite a lot over the space of a few seconds - if 802.11b did the same then this would likely affect something which was pegging the network at max...

Thanks for the notes on this!
