HVR-1600 on Vista Media Center Edition

(1/1)

norm:
Hi, I have a Hauppauge HVR-1600 on a Gigabyte GA-MA78GM-S2H, onboard ATI Radeon HD3200 video, 4GB base memory.

I have used this setup for the last year on XP MCE and VMC, both worked fine with the analog tuner of the card.  Our cable company switched from analog to all digital, so I have been attempting to configure the ATSC tuner on the card for the unencrypted QAM channels.  I have used VMC SP1, VMC SP2beta, and Windows 7, fresh installs with TV Pack and Playready.  Channel scan finds the QAM channels and everything works fine.  Until the playback buffer fills up to somewhere between 25 and 31 minutes, then I get the receiver service failure.  Scheduled recordings also fail at the same timeframe.  It seems like some buffer is getting filled up and causing media center to crash.

Many fresh installs with both x86 and x64 versions trying any possible solutions I could find.  bcdedit which always comes back clean, I've disabled DEP, tweaked service user accounts, applied all the patches, tried Vista Codec pack under Vista, and other random tweaks.  Nothing fixes it.  I have also tried different sets of 2GB memory alone to isolate any memory issues, but had the same results.

XP MCE does not support the QAM tuner otherwise i'd use it.  Windows 7 media center is very nice, if i would only work.  Any suggestions to help me get my HTPC back?

Thanks.
