For an HTPC I'd say get the MSI
K8NGM2-FID. Unlike the Asus model, the MSI comes with dvi, vga, svideo, and component out (svideo/component via bracket as seen in newegg's pics). With Asus it's a separate purchase.
I personally have some problems with my a8n-vm csm but am waiting on a new cpu as that's the only part I haven't replaced yet. Basically the MSI and Asus 6150 boards are the same except that the MSI has settable vdimm in the BIOS and it comes with the nice TV out bracket.
