@Mijo:
Hehe...After some testruns with my Girlfriend, I can tell you:
Zero Drops
FAQ: Check your EMail
My Computer:
I think I have done most of what you told me, but I will check it again now and tell you about my results. And if all of that is not working, I will capture MPEG2 with my ATI Prog, there I dont see the drops and can work with GKnot afterwards. I only have to fix this buggy sound
Edit:
My source is the Tuner of my VCR, video as well as audio
Edit2:
Ok, new resolution is 704*576 audio 48 hz, chunk size 512-1MB with 15 chunks, about 5 and a half minutes without any drops after that nearly more drops than capt frames. Strange...
