capture with 2 tuners at the same time

[dvd_maniac]

does anybody have any experience with capturing with multiple tuners at the same time? I have ATI AIW 9700 Pro and just purchased PVR-250. I am capturing through MMC with AIW and Snapstream BeyondTV with PVR-250. So far no problems. I am wondering how far I can push this. I have a pretty fast system and was wondering if I could handle 1 more tuner. I know it sounds like overkill and when could there possibly be three good things on at once? But it has more to do with back 2 back shows. I hate missing the begining or End and sometimes there are 2 things on at once. Plus I seem to be the record this and put it on dvd-r man with friends & family.... Oh well. Has anybody gotten 3 or more tuners to work together? If so, info please...

There is a little program.
Description is here (http://tuner.ixbt.com/soft/soft_tv_capture_015.html).
It's in Russian but you can look at the pictures.
Program needs WDM drivers for devices and tested with WinXP and DirectX 9.0. It uses video mixing renderer. No 98/ME support.
You can download it here (http://tuner.ixbt.com/soft/files/capt1.zip).
