I am about to replace my VCR with a Panasonic DMR E100HEBS, this has a 80gig HDD, it can record DVD Ram and DVD-R. I understand the principal of how a VCR works, but when it comes to digital, I confess to being at a loss trying to understand the difference between MPEG2, MPEG4, SD Cards and a lot of it's other features. I am not stupid and will learn, (eventually). Now I have a need to, and I will. There is one question though which is bothering me, it has arisen from reading some of the posts on here, and it is whether or not I will be recording a Digital or Analogue signal from my Sky receiver, if I connect it to my nice new toy, using a scart connection. I already know that I can record a Digital signal from my DVB Tele, but I am not sure what the position is with the SKY box. Any help would be appreciated, but please not too technical at this stage of my learning curve. I would also like to know if it's possible to replace the existing HDD with a bigger one, by just a straight swop. Or is it much more complicated than that.
