So the VuDuo is built by crappy (low quality?) capacitors, first C807 and now C848.
Lucky me for selling it and buying the Duo2 (I wonder what will suck in Duo2..).
I'm not 100% sure that all the vu+ duo are concerned, but i guess this is an issue on certain series of vu+ duo... as you can have this kind of issues on some TV, laptops or smartphones.
I bought my vu+ duo in May 2011, so far so good... never had to change a component on it (crossed fingers )
Since 2011, the receiver works 2-3 hours a day (its not that much) but till now, no problem.
vu+ duo 2 seems a good choice, and transcoding option is really a +
