I was planning on buying Sony SR47 (60 GB) hard drive camcorder, but I did not read too many good reviews on it.
($399.99)
Any suggestions??
Answer
Just to be clear - the Sony DCR-SR47 is an entry level, consumer grade, internal hard drive based camcorder. It is nowhere near "best".
Personally, I do not recommend internal hard drive based camcorders because of their known problems with vibration, loud audio, and high altitude... they can stop recording under these conditions. Flash memory and miniDV tape do not sffer from these problems. As well, HDD camcorders can be VERY challenging when the camcorder breaks and the video has not already been transferred to a computer. The removable media used by miniDV tape and flash memory can be used by other camcorders so access to the video is easier after camcorder failure.
The video file formats are the same when comparing HDD and flash memory - assuming the lenses and imaging chips are the same, the video quality from these camcorders is the same. The only difference is the storage media. Standard definition DV (used by miniDV tape based camcorders) is much less compressed and results in better video quality - again, assuming the lenses and imaging chips are the same size as the "equivalent" HDD and flash memory camcorders... MiniDV tape based camcorders require your computer to have a firewire port. HDD and flash memory camcorders use USB to copy the files - but many times those files need to be converted using a utility like MPEG StreamClip before a video editor can deal with it.
I strongly suggest you stay with miniDV tape (Sony DCR-HC62, Panasonic PV-GS320, Canon ZR960) or flash memory (Canon FS100) and skip hard disc drive camcorders. The ZR960 and FS100 have a mic jack (but no manual audio control) that other camcorders in this class do not have.

Why are there no 20 megapixel camcorders in market?

We all know that there are cmos sensors with 15 megapixels resolution but these sensors are only be used for fotografy,not video.So,i would ask,why not for video???Is that because there are technical problems(like huge bitrate or no good video compression software in 2010)or....why??
Ok,we need also tv's with 15 megapixel resolution too to enjoy our films!Why are there no such tv's and cameras?Thank you..

Answer
There is 39 megapixel camera:

A camcorder must embroider with the image when shooting. 39MP images must repeatedly come. If you want to record them, you must have really powerful GPU. Powerful GPUs are heated, then you must cool them with a fan etc. It means, If you want to use that camcorder, you should be muscled, it will be huge and heavy.
In the past, computers are huge like this and processors had low frequency. I believe it will be possible what you want in future, but now, impossible.

MegaPixels show us a picture dimensions NOT dpi. So If you want to play a video which is 15MP or higherMP, your TV must be huge screen. Like this:
24MP picture ----> 213,33 cm x 142,22 cm TV panel (72dpi).
It is realy hard to have it.
