My TV: Fastforward "jerky"

[igalan]

With this new version fastforwarding My TV (timeshift enabled) seems to be worse, it's a bit jerky. With previous versions it wasn't perfect, it jumped in little steps, but at a steady rate (not the super smooth fastforward that WinTV2000 has) . Now this is worse. Not a real problem, but it looks bad.
