Any tips on running multiple instances?

[xred]

I am having some stability problems and other issues getting multiple DVBDream instances to stay up and running.

I'm running two Twinhan 1020a cards under multiple instances of DVBDream (C:\DVBDream1, C:\DVBDream2). I'm using these instances as network encoders for SageTV (running MFury's SageDDModule) and I'm running on Vista Basic stripped down of all non-essential services (ie Indexing turned off, all skins and UAC off). I also have both instances set to use no decoder filters (null), and both start running with the /renderless and /minimize options at startup. Is there anything I can do to stabilize this setup?

I'm currently using the BDA drivers for the Twinhan cards as it appears to be the only driver DVBDream supports for multi-card setups. Any way to use WDM drivers in a multi-card setup with DVBDream?

TIA
