This explains the choppy playback. I don't know what level of
acceleration we have for G3, but here (P3-1.1GHz) i can play it very
smoothly with no frame drops. (cpu usage about 60%)

The stream ep2_clone_war_p640_bak.avi has indeed a dancing pts
behaviour. These are difference from expected pts values with audio
drift correction disabled:

audio diff = -2116 audio_drift = 0, pts_per_smpls = 66873
audio diff = 236 audio_drift = 0, pts_per_smpls = 66873
audio diff = 234 audio_drift = 0, pts_per_smpls = 66873
audio diff = 235 audio_drift = 0, pts_per_smpls = 66873
audio diff = 235 audio_drift = 0, pts_per_smpls = 66873
audio diff = 1018 audio_drift = 0, pts_per_smpls = 66873
audio diff = 235 audio_drift = 0, pts_per_smpls = 66873
audio diff = -2116 audio_drift = 0, pts_per_smpls = 66873

Do you mean more dropped frames? ffmpeg was updated recently but i don't
believe it would result in worse performance.
