BDA Drivers and HDHR Question

[Eckwell]

I just got an new HDHR and set it up using the instructions on the SiliconDust site and it is working, but the is stuttering and jumpy so I am trying to troubleshoot. I was wondering though, how do I know if it is using BDA drivers? Where do I check? And what is the benefit?

Thanks in advance for any help.

If you followed the instructions on Silicon dust's site in the last 2-3 weeks then you are using BDA drivers.

As for the stuttering, your specs look pretty resonable, could you try playing back the HDHR recordings in VLC, WMP, or something like that to see if they also stutter?

(According to your SIg your SageTV may be out of date, make sure you are running the latest 6.2 release)

FYI, if you plan to use 1 of the tuners for QAM and the other for OTA, I don't think this currently works using the BDA drivers.

If I am wrong, someone please speak up with a link on how to accomplish this. I could not pull it off using BDA and rolled back to the network encoders.

1) I wish your Avatar was a bobblehead. (I'll get over it)

2) The stuttering issue is common to everyone running source streams greater than 720x480 to display windows greater than 720x480. "I" don't have a stutter issue, but then my PC display is set at 1152x860 and I render HD in a window (with quick_menu_sizes=1152x608,1024x540,910x480) so I'm not one to talk and everyone should ignore me. 1920x1080i? I'll get some cardboard and simulate it.

I noticed that you don't have your HVR-1600 set up to capture ATSC or QAM, so you may not have run into source resolution bottleneck yet.

There are several running 'stuttering' threads currently on the forum to help with troubleshooting. Just know you have some great parts already assembled so you should be able to come up with a working solution.

3) BDA. Just to be clear, SiliconDust sets up SageTV to utilize the MS Broadcast_Driver_Architecture for capture -- (but their own Setup and GUI applications still launch VLC Media Player that connects using the Network Tuner protocols). I say this for people doing diagnostic troubleshooting so they don't confuse the two.

4) The BDA method is 'supposed' to be better. It allows SageTV to record the HDHR content directly into an MPEG2 data stream (and possibly correct data errors), otherwise you need to connect to the HDHR as a Network Encoder and get an MPEG2 data stream encapsulated and recorded to disk as a Program Stream (PS) or a Transport Stream (making it more difficult to work with).

So far there are a couple of major limitations with this method and I assume another method will be offered in the non-to-distant future. (68 channel limit, no ATSC and QAM simul capture).

* I also see that NEOSG has posted his question on the SiliconDust Forum, so I won't suggest he do what he already did. Though he might want to post that question again in a *NEW* SiliconDust thread to get Jafa's attention.

Thanks for the suggestion Conejo I submitted a ticket to be safe
