Or maybe its normal thing?
2500 frame insertions per hour is not normal. I normally record at -q 40 -d 1 with 10 or so insertions/deletions per hour, but I haven't done much recording from the composite in (-i n). -q 80 -d 1 also works fine for me except that I dont think the increased disk space usage is worth the extra quality. Are you recording from VHS? May be something to do with your VHS signal/tape quality? Have you tried recording from the tuner? What harddrives do you have? -- if IDE, check you have DMA enabled. Also, try measuring the drive performance by, say, hdparm -t. I have come across disk related bottlenecks in the past. Selva P.S.
