Here is what works for me:
1. I disabled aero interface (contrary to official recommendations)
2. I use ffdshow. This works the best for both - EIA-608 and EIA-708.
3. I use ASUS Nvidia GeForce GT 430 DirectCU Silent Fanless video card. I had stuttering problems using a similar but different video card.
You may have a different issue, so your logs will help the Team to narrow down the problem.
Please let us know what works for you. Somebody else might have a similar problem.
ffdshow subtitle filter instead of cc parser? or just ffsshow MPEG-2 Video Decoder?
I have an ASUS NVIDIA GT 240 so ours may be similar.
Thanks for the reply.
