SD clear QAM channels not playing (A100)

wpialum · 2009-02-12, 02:52 AM

I just purchased an HVR-1250 as a second digital tuner for clear QAM to complement my HVR-1600 ATSC and analog tuners.

When I did the channel scan, I noticed that in addition to the HD network channels, I also get a lot of the SD network channels over clear QAM. I can play these just fine through PVRX2 on my PC.

On the PCH A100, the QAM HD channels play quite well, but the SD QAM channels do not play at all. I get the "buffering" screen, and the network light flashes like it's ready for takeoff, but then it stops blinking, I get a black screen, and nothing happens. When I press "stop", I get back to the TV GUIDE and am able to try other channels.

On the server, the temp files are being created and are growing, so content is being stored, there just seems to be a problem getting this content to the PCH.

Anyone seen this? Any suggestions?
Thanks
Marc

After playing about a minute of live tv copy the mvp.....ts file from your temp folder to one of your video folders and see if it plays with your PCH and on your PC. If it plays only on your PC upload a sample to megaupload provide a link and I will have a look.

Grabbed 1 min of the regional news. Played fine on PC thru GBPVR, but would not play on PCH (got kicked out pretty quickly).

Thanks for taking a look: http://www.megaupload.com/?d=GPB04JR6

This is one of the typical problem files with the PCH. The hardware demux doesn't process it well, because (I think) the video stream is being interpreted as audio probably because of streamtype 0x80.

m> apid[0]= 0x0a40(0x80)= hdmv_lpcm audio

Running it through TS4NP will fix it for you which is usually a sign that Syabas won't try to fix it. This utility can be handy but it doesn't help livetv.

The software demux I am toying with does play it.

Thanks Martin. I'll just use the analog tuner on the HVR-1600 for my SD broadcast.

Thanks for everything you, Sub, and the rest of the community do. GBPVR and PCH is a wonderful system.
