Hi Vurbal:
I've installed and tried VirtualVCR on the XP box - seems fairly frustration free.
I have a couple of observations:-
Video format properties did indeed default to the NTSC version you intimated but I noticed your own example was showing PAL and being in Europe I originally thought I would need to set PAL as well. I did however leave it at the default NTSC and it seemed to work fine - confused!
When I tried to adjust the audio volume input level it refused any changes from the default -99db, although after I eventually reset the audio channels to mono I did seem to get the correct amount of audio from both speakers. Not an issue, just wondered why it wouldn't let me change it!
I also observed that the Default Video Frame setting was 320x240 as you can see from the image below
But, the preview monitor showed 640x480 which I believe is probably the source definition. Again, playback through VLC and just about everything else I've tried seems to be the correct ratio so it's probably not a problem - just more confusion. Yeah, you're right ...I seem to be easily confused.
I've attached below, the statistics produced by both VVCR and MediaInfo. If you could give them a quick look and verify they're what's to be expected it would be greatly appreciated.
Now I've got the potential to produce some truly massive unadulterated files, presumably all I need to do is any final editing and then save them out in an acceptable compressed format.
I did observe that both VLC Media Player and the editing monitor with Showbiz seemed to be reproducing as though it were a slow stream over the internet. Could that be because the x86 processor was struggling with the shear volume of data throughput or is it indicative of other issues. I've yet to try the same files and functions on this machine as I rather wanted to get my observations organised first. Will be assessing that as soon as I post this and will update as appropriate.
