Ok, Some very strange happenings. I tried live TV and found that the channels that were 1080 were also stuttering. The 720 channels and analog did not seem to stutter. While looking for a solution, I found this: DVBLogic • View topic - H264 Channels above 720P stutter
which talks about a similar issue, and of uninstalling the Shark Codecs to resolve the issue.
I did just that (after doing a reset all as indicated), rebooted, and I recieved a BSOD for DGMMS1.SYS. This time when the system rebooted, I went into media center to play a live tv channel, and the same BSOD. Upon reboot this time, I was able to play Live TV and it works great! (no Stutter).
REcorded TV on the same channels that caused me issues before now also show NO ISSUE!
I tried one of the original files that would not play in Media Center, but would play in Media Player (wtv) and it too played fine in media center. SO far, my recorded TV issues are fixed, and the live TV is working even for 1080 channels.
NOW, New Problem is that I can no longer play my MKV movie files(since I unloaded the Shark Codec).
The link above talks about reinstalling Shark codec and changing the settings manually, but I would have NO idea where to start with that.
Anyone know of a way to have my cake and eat it too?
