I would be surprised if one DVB card had more or less glitches than another. Glitches on DVB are more likely cause by bad reception so receiver sensitivity and worse S/N ratio would be the most likely causes. DVB satellites move around the sky in a figure of 8 shape, so depending on where your dish is pointing, the signal signal strength might vary over time. Was the S/N ratio the same on both cards? It might be that the hard disks are causing the problem or the filesystem. Which file system are you using? I know rieserfs is particularly bad for low latency application.
