I recently lost basic cable, making my SD MythTV system worthless for recording. So I bought an HD card, which works well to capture broadcast TV, but my system just doesn't have the power to play back HD without annoyingly jerky video and audio.
I don't have time now to start over with a new motherboard and CPU, but I'd like to make these OTA MPEG transport stream recordings watchable on the system somehow. It sounds like a video card with VDPAU support is not an option as I only have an AGP slot.
I am wondering if I could use ffmpeg to reduce the frame rate (or even reduce the resolution), but playing around with it shows that regular transcoding is super slow and has caused the audio to get out of sync with the video.
Anybody have a great kludge in mind, or is it time to bite the bullet and rebuild my system?
