Supported Tuners: which ones work, which ones do not?

[ptoal]

As part of a major system update, I've installed this card:
http://www.avermedia-usa.com/avertv/...il.aspx?Id=480

I'm running Windows 7 x64 on an AMD Athlon64 X2 4400+ system. I also have a Hauppauge PVR-150, and an HD Homerun connected.

This system is running Sage 7 Beta 7.0.11.232

The Card is detected by sage as: AVerMedia Cx23888 Video Capture.

The board is working well, except for 2 issues:

1. I am experiencing audio sync issues when recording with it. The audio lags the video by almost a full second.
2. I can't add the "Digital Capture" as a separate tuner in SageTV. The board only shows up as having a "Video Capture" option, which can be analog or digital. No idea how to add the second tuner to capture Clear QAM.

I'm thinking I will go and swap this board for an HVR-2250...

... And that's what I did. The HVR-2250 works great, was only $20 more at TigerDirect, and has 2x the tuners. That said, I'm having problem #2 with the HVR also... Maybe it's a Win7x64 or Sage7 issue...

DVB subtitles doesn't work as the card doesn't support it. I asked the question to Hauppage customer support after I couldn't see any DVB subtitle and they confirmed. However they didn't say if the problem is hardware or the drivers simply are not designed for that.
