The firewire connection is just for changing channels. Theoretically you should be able to transfer live video/audio out of your box using firewire but this is unreliable with Rogers boxes and/or impossible due to encryption. I have had more like with using firewire for channel changing with SA3250HD boxes than 4250HD boxes but others have it working with the 4250HDs.
The whole point of a PVR is to no longer have a live viewing experience. Comskip is a beautiful thing - just as the show is cutting to commercial you automatically skip right through to where the show picks up after commercial.
I have upgraded my HTPC to Windows 7 and I can no longer connect to my HD-PVR. In device manager the device is flagged as not working properly, and when I attempt to update the driver it says access denied.
The HD-PVR still works properly when connected to another computer running Vista.
Anybody knows what's going on? Thanks.
The Haupage website has a list of their products certified to work with Windows 7. The HD-PVR is NOT one of them. Hopefully they will correct this quickly as otherwise it appears to be a brick on Windows 7 computers.
It does make sense. The USB-UIRT slows down channel changes because it takes several seconds to recover from changes in input. It goes like this...
1. Small delay for STB to change channel.
2. Long delay for HD-PVR to sync to new analog data, buffer new data and deliver new digitally encoded data stream.
3. Small delay for HTPC software to buffer, decode and display new video/audio.
The HD-PVR is definitely the slow link when live TV is being watched and channels, or any other analog data stream attributes, are changed.
And this is why when I am finished recording one show from my PVR, and stop and erase it, The HD PVR stops working, and I have to turn it off and on, and hit refresh in Arcsoft... isn't it?
is there any way to change the default input default resolution of 1080p (1920 x 1080) to 720p? the files can be huge if you record a 2+ hour movie
It is unlikely that you are recording in 1080p as the HD-PVR records in the resolution that it is receiving from the device it is connected to - generally your cable or satellite box. And 1080p is not used for broadcast HD - but 720p or 1080i are. That being said with Rogers cable boxes you can fix the output to either 108i or 720p.
The second factor is the bitrate that you record and that is generally set in the software that you are using - for example Arcsoft, SageTV, MythTV, etc. You can set it to lower rate to reduce file size at the risk of reducing quality.
Ever since my father upgraded to Windows 7 he has lost optical audio through the HD-PVR to Sage TV. He can get anolog stereo to work. Is there a setting somewhere in the HD-PVR or SageTV that needs to be reset?
