The reason I'm keeping Voom is a matter of process by elimination. My needs are local team sports, an affordable HD DVR, and good HD programming.
1. Cable: HD package hasterrilble PQ and so bandwidth constrained they can't add any more HD channels, even locals. I subscribe to basic to get my RSN.
2. D*: I have to use Pegasus. D* HD upfront costs are high and they haven't shown enough of a commitment to make me want to get locked into a long term contract. HD Tivo will be unaffordable for at least a year.
3. E*: I have twice signed up only to cancel before install. My main concerns are buggy hardware and the fact that they don't offer existing customers upgrade offers. They could potentially have an affordable HD recorder by the end of the year. But I have read enough to know seeing is beleiving w/ their hardware.
4. V*: Big holes in both HD and SD lineup. STB bugs (mapping, audio drop outs on quick flipping, frame rate loss, occasional blackouts) affect me much. Content on Voom originals is 90% crap, and Divine kinda pissed me off. Voom is still the HD leader. They're new, so I maintain some hope they'll get better. What makes me a huge sucker is that I kinda think the DVR will be both good quality and affordable when it is released later this year. New mpeg4/wma and new sat. could help.
I am sticking with Voom b/c of potential, and the fact that there is no "good" choice out there. But, as I said in other places, I can no longer recommend Voom to my friends and family.
