Today I faced with strange problem. I installed a fresh 0710 RC2 core/hybrid and choose VDR as PVR system. VDR worked fine on the core. But when I added a new MD, I couldn't find any VDR packages there. The box 'VDR' was ticked on the Software module page, the device VDR existed (I saw its log) but there were no any VDR packages on the MD. After rebuilding MD's image the VDR packages were installed.
I haven't seen such case in my practice. Any idea why it happened?
