[mythtv-users] Stutter with a P3 933Mhz! Gezzz - more STUTTER!

[john roberts]

I haven't changed any of the default settings for:

- Capture resolution
- Encoding

TOP shows the CPU busy about 70%.  At this point - I don't think it's a CPU speed issue - since I was orig using a P3 500Mhz and it was performing about the same.  Stutter may have gotten a bit better.

What capture resolution/encoding are you using?
