Two Fusion 5 - Can't record two shows at once

[alex9k]

I am using a Fusion 5 Lite for OTA ATSC HD and a PVR 250 for analog recording. I get great results.

I added a second F5 card and I can not record two HD programs at once. I've verified that each card works and will record if the other F5 card is not recording. I can have one F5 card recording and the other will do live tv. Once I start a second recording, the first recording will continue fine but the second will produce a 6KB dvr-ms file.

The fusion app works fine with both tuners recording simultaneously. I am aware the fusion app uses the WDM drivers and GBPVR uses the BDA drivers which are not as advanced.

If anyone else has two fusion 5 cards recording at once, I'd like some tips on how I could get it working. I'm using the dvr-ms mux.

System specs:
Intel P4 2.8Ghz
Intel Chipset
1 GB RAM
Tuners: Happauge PVR 250, 2 Fusion 5 Lite
Video: ATI AIW 9000 (Only using vid card)
2 SATA WD 80GB spanned to 160GB
XP Pro SP2

I dont think anyone has ever tested this before, so may not be possible. All I can really suggest is trying a different mux. If that doesnt work, you might have to hope newer dvico drivers fix it.
