Questions during upgrade to latest version of GBPVR

[topperdude]

Hey Guys,

I've started the process of upgrading my GBPVR setup to the most recent version so I can use the HVR-1600 for clearQAM tuning and (hopefully/eventually) with a NMT as the client device. I would like to use this thread to track my progress and any issues I run into.

Story so far:
Installed WinXP MCE 2005 with all the necessary updates and then installed the hauppauge software from their website (both the drivers as well as the WinTV 6 application). Also installed the basic Via audio driver for the on-board audio on my PC Chips M811 board. I then fired up MCE as a test and confirmed it was tuning the analog channels as expected.

Then ran MC2XML twice to generate the XML listing files for the analog and digital sides, fired up GBPVR config and added the analog tuner. Next, I switched the RG6 cable from the analog to the digital input on the HVR-1600 and went into GBPVR config again to add the ClearQAM source and scanned for and mapped only the local NBC channel to the appropriate channel in the guide for test purposes. Now the fun starts:

a) When I went into PVRX2 and brought up the guide, it listed the guide for the analog side as expected. But the clearQAM channel I had mapped kept saying something similar to "no show information". Not sure why?

b) Even though the guide didnt show the program data, I was able to manually record about 10 minutes of the show (Tonite show with Jay Leno) thru the clearQAM tuner using the DVR_MS mux and then with the TS mux. Noticed (in Gspot as well as WMP and VLC on a different computer) that the generated files (with both multiplexers) were in the expected HD resolution (1080i), but audio was only 2-channel stereo. My understanding is that this show is broadcast with 5.1 sound, so am wondering if I need to install an audio codec to get the 5.1 sound? I havent installed any audio drivers since I understand sub has mentioned in the past that for digital TV, it doesnt use any separate encoders and the raw audio/video stream is directly dumped on the hdd. So what am I missing to get 5.1 sound? Thoughts?

Thanks,

Anyone?

Does AC3filter audio decoder give 5.1 sound?

Good Luck

Edit: Ooops! I now see that you are already there.

If you use a utility like MediaInfo does it show that the files has 5.1 audio. If it has 5.1 then it is going to be a playback issue like a codec. As far as I know while recording there is nothing you need to do to get 5.1 it just dumps the stream to your hdd as you said.

Perhaps there are 2 audio streams, and GBPVR is selecting the first one to record?
If you do a quick recording of a 5.1 show using the Full TS Mux, does it show 2 audio streams in mediainfo?

Thanks for the replies guys! Looks like that show may not have had 5.1 sound. In the past week, our cable provider remapped the HD QAM channels. So today I finally got around to re-scanning the QAM channels and mapping the channels. Then did a test record of CSI: Miami and streamed it to my Xbox. Although video was stuttering (as expected), the audio showed DD 5.1 on the receiver. So not sure if something changed from the provider or the show itself didnt have 5.1 sound.

Interestingly, neither Gspot nor MediaInfo showed information about the audio or video resolution (could this be because I am using TS mux?). In either case, next step is for me to figure out how to transcode the file so that the video is a lower resolution so I can play it back on NTSC TV with AC3/5.1 audio intact. I looked at the AutoTranscode + Cut utility in the wiki but not sure which setting I should use. Thoughts/advice?

Also, I while playing back (and skipping forward, backwards, etc) some of the clips recorded tonite, PVRX2 crashed a couple times. Have attached the logs. Would appreciate some feedback of what could be causing this?

Thanks,

Edit: Just recorded few minutes of Tonite Show tonite again and it looks like this show is still in 2.0 AC3 format.
