Hi,
I've started using PVRX2 (1.1.5 and also just switched to 1.2.9 now) with HVR-1600 to view QAM channels. I am using Windows XP SP2 on a Core Duo 2.8GHz 2GB RAM with latest Hauppauge driver (Jan 2008). I am seeing a problem when changing channel--there will be super-slow-motion video when switching to a channel.
Occasionally, I would see the "No signal detected ..." dialog with signal Quality @ 100% and Strength 0% (it would sometimes switch between 100% Quality/0% Strength and 0% Quality/100% strength), and I would see no video/freezed video/slow-motion video.
This seems to always occur to certain channels.
This problem never occurs when using WinTV 6 from Hauppauge for those same QAM channels. I can always change to those same channels with no problems and video would play fine in WinTV 6.
Using Hauppauge's signal montior, I can see the signal strength to be about SNR 31.2-32 during the time I see the problem w/ PVRX2 with that channel, depending on the channel/condition of the time. I assume this should be good enough signal strength as WinTV 6 has no problems displaying video when chaning to the same channel.
I tried several workaround's:
- if I switch to another channel and switch back to this channel in PVRX2 once or twice, the problem goes away and video plays normally again.
- if I quit PVRX2, relaunch, and then select Live TV from the main menu, I can always successfully view this channel w/o the no video/freezed/slow-motion video issue (so far).
However, the "No signal detected" dialog would sometimes come up despite video plays fine when viewing this channel right after relaunch. You can actually see the dialog over the video which is playing behind. This seems to occur the most if I go to Live TV to that channel right after launching PVRX2. I have to switch to main menu and switch back to Live TV to dismiss this dialog.
I tried setting 'BDADisableStatusChecks' to 'true' but that only dismisses the dialog and does not clear up the slow motion video issue during channel change.
This occurs with both GBPVR and PVRX2 and both in 1.1.5 and in current 1.2.9 and is happening for certain channels everyday.
Also, I notice the QAM physical channel numbers found by Config for quite many QAM channels are not the same as the numbers found by SageTV--they seem to be a bit off (for example, 107.7 instead of 107.9). I think the channel numbers from SageTV is correct as I also tried another tuner and found the channel numbers for same channels to match SageTV's.
thx
