[mythtv-users] Re: PVR-250, weak machine, and disk speed

[Andrew Ingram]

I've got a PVR 250 in a P2 450Mhz. Capture obviously is no problem, uses
1% CPU. However the playback is stuttery and not very good. I've tried
changing resolutions but this doesn't help. I think it relates to the
bitrate that the PVR250 uses, which is locked to 16Mb/s. There is
support going into the driver to allow changing of this, and I'm sure
that MythTV will support the changing of the bit rate as soon as this is
all sorted and stable. Until then, a machine as slow as my 450 (or
slower) is no good as a replay machine.

You could always add a Promise ATA/100 (or better) PCI card and connect
the recording drive to that.

My intentions are to try the PVR250 on my 'spare' PII 350 with a Promise
card.
