Back in January (http://www.avsforum.com/avs-vb/showt...6#post15473506
) I asked about a problem with severe pixelation, freezing and audio dropouts when VLC was invoked from hdhomerun_setup.exe but not from TSReader Lite. Either way cranks my old, slow CPU to 100%. Recently I found the solution. If I set the priority of hdhomerun_setup higher than that of VLC it plays as well as it does from TSRL. Upping both equally or setting VLC higher doesn't help. Neither Task Manager nor SysInternals' Process Explorer change the priority permanently, so I'm using Process Lasso (http://www.bitsum.com/prolasso.php
) which sets the priority every time the app runs.
The result is still too jerky for normal viewing (looks like 15 fps) but it's OK for monitoring purposes. I use a MyHD card to watch what I've recorded.
Is there a way to use MPC-HC instead of VLC for HDHR monitoring?
The only problem I've had with HDHR recordings (using CW_EPG to schedule it and the MyHD card) was that I'd get a couple of seconds of signal loss every few minutes from the HDHR but not from the MyHD using the same sources. I suspect the computer sometimes was busy doing something else and dropped some packets. That's what happened years ago when serial port speeds started to increase; it was fixed then by the introduction of the buffered UART. The SiliconDust FAQ had some suggested fixes but the 10/100 port I was using (nVidia nForce MCP) didn't have any relevant options to change. The MB also has a Marvell Yukon Gigabit port with more options, so I switched to that, raised the buffers to maximum and replaced my 10/100 switch between the HTPC and HDHR with a gigabit one. That seems to have cured the problem, although I'm so far behind with my viewing that it's hard to be sure yet. I doubt that the extra speed helped, but the extra buffering may have.
I wish there were an up-to-date alternative to the MyHD card with hardware decoding of all the new formats, but until there is, this venerable card together with one or more HDHRs all scheduled by CW_EPG makes for a nearly ideal HTPC.
