Post subject:  blurred playback w/ PVR-250
When viewing captured video or live TV, I see what I can only describe as "dropped frames" on the high motion scenes. In other words, if something is "moving fast" in the show, like scrolling credits or a fast fight scene for example. The video does not move fluidly, rather it's a bit choppy. I know I'm not dropping frames because my PVR-250 is doing all the encoding work; plus everything else looks fine -- it's just the fast motion scenes. I think my problem might be in the recording settings. Has anyone else experienced this?

I'm capturing analog cable using MPEG-2 PS, 5500 kbps / 7000 max; audio settings are 320 kbps/44 kHz. The rest of the hardware is as follows: ASUS A7N8X-VM, AMD 1900+ tbird / 512 meg RAM (PC2100), seagate 8 meg cache 160 gig drive running Knoppmyth R4 and patched to 0.13 of mythtv.

check your /var/log/messages

If you have lines in there that say something about no free buffers (I can't remember the exact verbage off the top of my head) then you are dropping frames.

Nothing there about it, XS. I don't think it's really dropping frames... probably some recording setting I don't have tweaked. Does anyone else see this on fast motion caps? Do I need more than 5500/7000 kbps?

No info about free buffers..., but I did find:

Feb 16 19:31:29 mythtv kernel: 0: NVRM: AGPGART: unable to retrieve symbol table
Feb 16 19:31:29 mythtv kernel: ivtv: ivtv-api.c: unknown ioctl 0x803c7601

I also have:

Feb 16 19:31:22 mythtv kernel: hda: dma_intr: error=0x84 { DriveStatusError BadCRC }
etc...etc..

Is this bad? Video is 95% exellent. 5% choppy, or slightly dropped frames, really only noticeable when watching sports (Hockey) :P
